I don't know if it's still prevalent, but I've heard of a... routine where some sellers will sell an item, stretch the delivery date out, and if the item's cost goes down, release it to be shipped. If the price starts trending up, they sit on it and cancel it, later listing for a higher price, basically speculation and attrition. Edit: I WILL take a moment to complain about getting higher prices on items when signed in on an account than incognito. Sign in and they jump back up.
