Having worked in retail for quite a time....I can tell you that credit card refunds do not go thru RIGHT AWAY. Depending on when and how the store processed them it usually takes a few days to go thru and even then they may not show up for awhile..even to your next statement. I know that doesn't sound fair or right but sometimes this is how it works. As for being charged twice it sounds like there was a bit of confusion amongst the clerks and people in charge of this. From the sounds of things the store was not really as well prepared for this as you would think they should be. It happens in retail all the time. My advice to you all is to wait a few days....it seems like the store had way more phone orders than they normally do...especially since this info was on a few websites and people who could not attend found out about it and ordered over the phone. Those of you who were overcharged...wait until you receive the books....if you get the proper order (the number you requested) and are over or undercharged THEN contact the store. Its really best to wait until the books arrive...then the store clerk can remedy the situation for you. Because of the demand via phone there may be some delays...but wait until you receive the merchandise first! Just my 2 cents worth!
