It's called escrow hedging - vendors can choose to enable or disable it, and it tells you if they are hedging an order when you add it to your cart. If you don't want to deal with the possibility of losing money on a canceled order that is hedged, then use a vendor who doesn't use escrow hedging. This is all info that is readily available - please take the time to read up on these things before placing an order so you understand the possibilities.
