Just curious --- In the two specific eBay auctions referenced above (one where there was a $7.50 charge for shipping and handling, and one where there was a $15.50 charge for shipping and handling), did the sellers not indicate in their respective auctions that they would be charging those specific amounts as shipping and handling? (So, in other words, were you were both caught off guard when all of a sudden these were the amounts included as shipping and handling?)

If the sellers did not disclose exactly what they were charging for shipping and handling in the listing, then I agree it was very unfair and they deserve a poor rating. If, however, the $7.50 and $15.50, respectively, was disclosed in the listings as the amounts that would be charged to the winners as S&H (and thus you knew exactly the amount you were going to be charged for S&H before you decided to bid and thus you could have taken that into account in deciding how much to bid), then that's a very different situation.
