Hot Deals Feed: AI-Scored Cashback Rate Spikes and Opportunities

#What Are Hot Deals?

Hot deals are portal cashback rate opportunities that the CashBackStacks scoring system has flagged as significantly above normal. The system tracks rates across 50+ portals and 48,000+ stores daily, compares current rates against historical baselines, and surfaces the most notable spikes through the Hot Deals feed.

Unlike static deal lists that are manually curated, the Hot Deals feed is powered by an ML scoring pipeline that evaluates every rate change against 30-day and 1-year baselines, factors in spike magnitude and historical rarity, and assigns a heat score that determines each deal's ranking and tier.

#How Deal Scoring Works

Every day, the scoring pipeline:

1. Fetches current rates from all 50+ tracked portals for every store
2. Compares against baselines: 30-day moving average and 1-year historical range
3. Calculates spike magnitude: How far above the baseline the current rate sits
4. Assesses rarity: How often this portal has offered a rate this high for this store
5. Weighs portal reliability: Established portals with consistent payout histories score higher
6. Assigns a heat score: A composite metric that maps to discrete heat tiers

The result is a ranked feed of deals where the most exceptional and time-sensitive opportunities float to the top. The scoring is fully automated, with no manual curation or editorial bias.

#Heat Tiers Explained

Heat scores map to three tiers, each indicating the statistical significance of the rate spike:

Warm: The rate is in the top ~25% of recent activity for this store-portal pair. It is above average and worth noting, but not exceptional. These deals can still represent meaningful savings if they align with a planned purchase.

Hot: Top ~10%. The rate is notably higher than usual: a genuine promotional spike or competitive push. These rates are typically time-limited and worth acting on if you shop at the store.

Blazing: Top ~3%. An exceptional rate spike that rarely occurs for this store. Blazing deals often signal aggressive promotional events, holiday pushes, or portal competition for a high-value retailer. Act quickly. These rates can revert within hours or days.

The deals page displays a fire rating (1–3 flames) corresponding to these tiers, making it easy to scan for the highest-urgency opportunities.

#Deal Types

The feed categorizes deals by the nature of the opportunity:

Money-Maker: The cashback rate exceeds 100% of the purchase price. You earn more in cashback than you spend. These are rare, promotional, and typically portal-specific with terms and conditions. Always verify the fine print.

Top Rate: This store currently ranks in the top 5% of all stores by cashback or rebate value. An objectively high rate regardless of whether it is a temporary spike or a stable offer.

Elevated: The rate is meaningfully above this store's historical norm, based on 30-day and 1-year baselines. A solid above-average opportunity driven by a promotional boost or competitive pressure.

ATH (All-Time High): The highest rate ever recorded for this store across all portals in our tracking history. All-time highs are rare and often short-lived.

Novel: The rate exceeds anything seen for this store in the last 90 days by a significant margin. This indicates a new pricing level that has not been tested before, which often signals a fresh promotional push.

Filter chips at the top of the feed let you narrow to a specific deal type. Combining type filters with heat tier filters produces highly targeted results.

#Urgency Signals

Beyond heat tiers, deals carry urgency indicators that help you decide whether to act now or wait:

Watch: The rate is building momentum. It may still be climbing and could reach a higher tier. Keep an eye on it.

Spike: The model predicts this rate will drop back within 90 days. The current rate is likely a temporary boost driven by a promotional push or competitive pressure. Time-sensitive.

Imminent: Based on historical patterns, this rate is likely ending soon. The portal has a track record of running this rate level for a limited duration. Highest urgency.

These signals combine with heat tiers to create a comprehensive urgency profile. A Blazing deal with an Imminent urgency signal is the highest-priority opportunity in the feed.

#Timing Filters

Two timing filters help you focus on the most relevant opportunities:

Fresh: Deals where the rate was elevated within the last two days. Useful for catching new promotions before they expire or become widely known.

Winding Down: Deals where the rate has started declining from its peak. These may still be active but are likely in their final hours. If you were planning to use this deal, now is the time.

#Cashback vs. Rebate

The feed includes two types of portal rewards, classified by how the rate scales with your purchase:

Cashback (%): Per-dollar rates that scale with your purchase amount. This includes percentage cashback (e.g., 5% back), miles per dollar (e.g., 4x miles/$), and points per dollar. The most common reward type. The more you spend, the more you earn.

Rebate ($): Fixed-amount rewards that do not scale with purchase size. This includes flat dollar bonuses (e.g., "$50 back on any purchase"), flat miles (e.g., "2,500 miles"), and spend-threshold offers (e.g., "Spend $200, earn $30"). The payout is the same regardless of order total.

A filter chip lets you show only cashback deals, only rebate deals, or both. CashBackStacks normalizes all rates to a comparable value, but some shoppers prefer to filter by reward type based on their spending patterns and portal preferences.

#The Cashback Heatmap (Premium)

Premium subscribers have access to the visual heatmap: a treemap visualization of the top ~100 deals, sized and colored by how far above the 30-day average each rate sits.

The heatmap provides a quick visual scan for:

• Outliers: Deals that are far above average stand out as oversized, brightly colored blocks
• Category patterns: Clusters of elevated rates in specific retail categories can indicate industry-wide promotional events
• Portal patterns: When one portal dominates the heatmap, it may be running a site-wide promotion

Free users see a preview prompt with an upgrade CTA. The heatmap data comes from the same scoring pipeline as the feed itself.

#Deal Evidence (Premium)

Each deal's signal is backed by an evidence string: a human-readable explanation of why the deal was flagged. Examples:

• "Nike at 12% via TopCashback is 3x the 30-day average of 4%"
• "Best Buy at 8% via Rakuten: highest rate in 6 months"
• "Macy's at 15% via BeFrugal: new all-time high across all portals"

Evidence strings are generated by the scoring pipeline and provide the context needed to make an informed decision. They appear in deal detail views and in AI assistant responses about specific deals.

Free users see the deal and its heat tier but not the evidence string.

#Personalization

When signed in with the browser extension, the deals feed enhances each row with:

• Your card's earning rate: The credit card from your portfolio that earns the most at each store, with its rate displayed alongside the portal rate
• Personalized total: The combined portal + card value using your actual cards, not generic estimates

This turns the deals feed from a portal-only view into a personalized stacking view. A deal that looks modest at 5% portal cashback might be excellent when your 5% category card adds another layer. The website reads your extension data through a local in-browser bridge; your cards and offers never leave your browser.

#Combining Deals with Stacking

A hot deal is the portal layer: Layer 1 of the cashback stacking framework. To maximize its value, combine it with the other layers:

1. Find a hot deal in the deals feed (e.g., Nike at 12% via TopCashback)
2. Check the portal rate using the live comparison below
3. Use the right credit card for the store's category (see the card portfolio guide)
4. Activate card-linked offers for the store if available (see how to sync offers)
5. Compare the gift card path: if a discounted gift card beats the portal stack, switch paths
