Can I get the difference back?
Can I get the difference back? For requests like "I bought a TV at Best Buy 9 days ago for $499 and it's $449 now, can I get the difference?". 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)
