Personally I'd tend to let it go. Even a record store owner might look at you weird if you returned a record for a small crease. I think it's fairly common.

The few mail order LPs I've bought (mostly from Sub Pop) have arrived in better shape in fact than most new records I see in the store. Think about all the people in stores, after all, who are handling those records, from the clerks who put them out to the customers who pick them up and carry them around, etc., before putting them back or whatever.
