Here’s what consumers have asked with answers from Beezid staff and previous consumers.
I myself, always use a credit card. I'm not sure if they accept money orders or not. Even if that is an option, I'd stick with a credit card simply for the benefit of the security offered by the card, such as tracking my purchases, someone else dealing with the headache if anything goes wrong with receiving the item, if on the off chance wha I receive isn't what I purchased, etc.
