Just to clarify, there's a difference between a "pending" or "authorization" transaction and an actual charge. This form of verification is common and if you look closely, you'll all probably see that these transactions never actually turn into actual charges. So there's no $1 "tacked on", no money taken out of your account, and there's no dollar to "get back".
Just watch your account and only worry if any of these transactions actually convert to charges (which they most likely will not ever do).
