Good at taking the money, good at not caring. Myself (and a few others) have been charged for pdf purchases and not receiving the files. Drivethrurpg CS are all to quick to wash their hands of it. "We don't see the transaction on our severs, so there's nothing we can do" (even if you include screenshots, receipts and my bank says they got the money). "Its a new a problem we don't understand, so there's nothing we can do" etc etc.

Low prices for low quality.
Be careful of multiple ringups for one item. Check your receipts no really check them.
Be careful of expiration dates. Check the dates if you can. They can be out of date or possibly reworked or smudged out.
Asking for help or if help is offered turns out to be pointless. Customer service is problematic for the workers there. Being a step up from dollars stores doesn't justify their attitude.
