🟢get_store_policy(store, item, country)
A store's price adjustment and price match policy.

With an item name it adds links to check today's price.

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)
