I wish ebay included the shipping in the total price, so when you are browsing through all the items, you don't click on one that looks low only to be deceived by how expensive it really is with shipping added.
Good Idea, but it would be hard to post an amount on multiple items (if you were allowed to buy numerous items in the same auction) and since shipping is often determined by zip code to zip code distance, very hard to do I bet.
Often on my auctions I will set a price on shipping that covers most of the US (some will cheaper for me to mail to, some will cost a little more). Buyers like to know before they click "yes". Priority mail has a great one rate package of $7.70 anywhere in the US mainland and for any weight in the box. I wish they offered that in more sizes so I could put more exact shipping costs on my auctions.
