I enrolled with C7L, the one where it asks for your credit card, and I get to the end and my total charge is $12.89. Cool, that's fine. I check out my bank statement online and there's a pending $12.89 charge. Great, I think to myself! My application was accepted. So, today I check my bank statement and the $12.89 charge is gone and in its place is a $13.67 charge from Columbia House. What's the deal with the extra 78 cents? Anyone have this happen?

I used the same code this past weekend and chose to be billed (I've already received the approval email), but I did notice at the end that it said the total may not include any applicable taxes. That's probably the difference.

That's just the sales tax for your state. CH always does that.
