Has anyone experienced this?

Recently, noticed a couple of fairly large Ebay charges on my credit card that were not mine...and, not long after, there was a credit that backed out the charges.  Should I be concerned about this?

Had you made any offers or was there any bidding activity at all around the time of these charges?

My kneejerk reaction is that you had bid or made offers on items. If you didn't win, the pending charges will disappear.

No.  We were traveling when the 2 different amts posted and then backed out.  Besides, the amts were over $200 and over $600...which is way beyond what I would bid on.
