Says whether a claim is likely (likely, likely_if_member, unlikely, check or no_drop), the amount, and the steps. With an item name it adds a Cheapest Price link and Amazon and eBay links to check today's price. Likely claims also get claim_message, ready to paste into the store's chat or email. policy.refund_paid_as flags stores that pay store credit (Newegg)

Calendar reminder for the last day to claim a price drop. Returns a calendar file (.ics) with an all-day event on the store's last claim day, how to claim and the policy link, with alerts 3 days before and on the day. Nothing is stored. check_price_drop_claim gives this link as add_to_calendar when purchase_date is given and a claim is likely.

Discovered

A store's price adjustment and price match policy. For requests like "does Target do price matching?", "does John Lewis refund if the price drops?", "Currys price promise", "what's Best Buy's price adjustment policy?", "will Costco refund the difference?".
