More and more often, a hot book crops up and AA pricing is way off base. Example, the Spider-Man #7 spoiler cover. Completed sales in the last week range from $30-$40 range. But AA has it at $3.99. I know that for hot books, it can be tough to keep up and that is perfectly understandable.
What I would like to see is the ability to lock the price in my CB database for individual issues, so that a subsequent downloaded update of the database doesn't change it. I've got a few copies for sale at $39 on AA right now, but the next update will set them back to $3.99, unless i stop CB from updating all prices for all books. Would be nice to have a check box right next to the "Sale" check bock that would prevent updates of the price, but only if that box was checked.
