Sellers holding feedback is BS even though they all do it. Its a sellers way of being 12yr old kids. So they as stated have an opportunity to bash you back if you say something bad about them. Reality is if the buyer pays in the alloted time they deserve positive feedback. Because that is their only job to pay you "the seller" they dont have to like the product or the shipping costs etc. Holding feedback hostage is only a way of maintaining positive feedback even if your a crappy seller. The desire to cover ones ass in a business sense is very understandable though. Many ppl rely on that extra income to build skis etc so while my opinion as a buyer is stated above I cannot say I wouldnt hold feedback as well after selling enough items and dealing with the average customer enough times. One can get understandably irritated. This is also why I really dont use ebay much anymore.
