In my case it was Vizio TV that went on sale for $600 less 3 weeks after purchase. A simple phone call brought $650, including tax, back into the account.For what it's worth, many years ago I bought an HP scanner from Costco for $400. Imagine my surprise when, after a week or thereabouts, I got a mailer stating that it was on sale for $60 less. I was able to take my receipt to customer service and they agreed to take it back (virtually) and then sell it to me again at the lower price. Worth a shot!
