Some sellers are actually nice enough to let you cancel the order and redo it before 45 days. Obvioulsy too much effort for a long term preorder but if it is a good enough deal then it can be worth the hassle. If they won't cancel then you let Paypal know they are not sending anything.
to me, no deal is good enough that would convince me to do a preorder on ebay. the percentages are way too high to risk doing something that will probably come back to make you regret it. for every one story of a transaction like that , that turned out well, there's hundreds more that turn out horrible for the buyer. for people who do this, you guys are extremely ballsy, you're essentially swimming with sharks.
