Every competitor sale, markdown and promo code, including the ones that only arrive by newsletter or SMS, validated in the cart so you know what they really take off and which brands they exclude. Brands breaking their own MAP, caught the same day.
Competitor promotion tracking records every sale, markdown, coupon and promo code a competitor runs, with its depth, scope and dates, so your own promotional calendar is planned against what they actually did. Promotion monitoring tools built on page crawls see the banner and the strikethrough price. They miss the code that arrived by email, and they never test whether an exclusion holds in the cart.
Lightfeed captures the codes where they are sent, validates them against your catalog without buying anything, and records the effective price, so brand exclusions and MAP are checked on facts rather than fine print.
A price tracker sees the banner. The price your customer actually pays is set by a code in their inbox and by exclusions that may or may not be enforced at the till.
A 20% code sent to subscribers never appears on the site. Competitors use it precisely so your price match and your crawler cannot see it. By the time it reaches a coupon aggregator the sale is over.
"Excludes selected brands" in the fine print is a promise to those brands. When the code still works on them in the cart, the competitor is below MAP and you are the one holding the line.
Someone screenshots competitor emails into a shared folder and types the dates into a sheet. Depth, scope and whether the code actually worked are guesses.
Your products with brand, SKU and price, the competitors to read, and the brands whose MAP you are held to. Add the brands' own sites to catch them undercutting you.
Shelf price, sale price, member price, promotion text and its end date, stock, on each competitor, matched to your catalog like for like.
Lightfeed subscribes to each competitor's newsletter and SMS list with its own addresses and numbers and extracts every code, its stated scope and its dates as the messages arrive.
Each code is applied to a cart of your tracked products. We record what it really took off, which items it refused, and flag any brand that landed below MAP. Nothing is bought.
| Field | What we record |
|---|---|
| Code and source | The code, the channel it came from (site banner, newsletter, SMS, cart prompt), when it arrived and the message it came in. |
| Stated scope | Discount, minimum basket, start and end dates, and the exclusions as written in the fine print. |
| Tested scope | Which of your tracked products the code applied to in the cart and which it refused, with the cart totals. |
| Effective price | Advertised price, discount taken, effective price per item, and the gap to MAP for the brands you named. |
| Status | Live, expired, revoked early, or re-validated before its end date. |
| View | What it answers |
|---|---|
| Promo calendar | Every competitor's promotions and codes on one timeline, with depth, scope and validated status, so your own calendar is planned against what they actually ran. |
| Code library | Each code with its source, stated and tested scope, and effective prices on your catalog. |
| Exclusions check | Brands a competitor says are excluded next to what the cart actually did, so a retailer that breaks a brand's MAP through a store-wide code is documented. |
| MAP compliance | Retailers and brands' own sites below MAP on the brands you named, with the listing or cart as evidence and an export for the brand conversation. |
| What changed | New promotion, promotion ended, new code, code revoked, price up or down, since the last run. |
| Delivery | The web app, CSV exports, a JSON API, and an MCP server for Claude or your own agents. Enterprise adds Snowflake, BigQuery and Power BI delivery. |
