You deserve to know that cancellations cost sellers time and money and most sellers aren't too happy to see them! Sellers pay fees to sell here and we are charged fees again when items sell. The money is taken right away... GONE! Some of it we'll never get back, and to recoup a small portion of it, we sometimes have to spend time doing extra work to apply for the fees to be refunded. Sometimes, cancellations also work against our selling record with Ebay. They shouldn't, but they do, although they are no fault of our own! It's buyers who don't want to fulfill their side of the agreement who cause all this disruption and aggravation.
A lot of sellers would never tell you these things, but I feel buyers need to know it's no easy bed of roses to be a seller here under the best of circumstances, and worse when buyers waste our time and money. Also, sellers are under NO obligation to cancel a transaction as per Ebay rules. If you find a seller who will do that for you, it's a big courtesy, and you should be very grateful.
Keep in mind that seller will have to spend time dealing with your problem (as opposed to spending time with their family or productively working) and you will probably be blocked from bidding or buying from him/her in the future.
Maybe you should just await the arrival of the item and give it to someone else as a gift, or donate it to a worthy cause. You'll feel a lot better about yourself if you do.
