Went to a dispensary last night and bought some CBD. They mentioned that if I paid by card it would cost a few dollars extra in fees. I paid with my debit card and noticed later that the charge showed up as an ATM withdrawal. Their point-of-sale device looked pretty normal, definitely not like an ATM. The place was fairy upscale - not shady at all, so I figured there must be a good reason they accept payments this way. After some research I found out that they do this because banks will often reject payments to dispensaries since weed is still federally illegal, and performing an ATM withdrawal for the exact amount needed allows for dispensaries to bypass this. I paid $5.50 in fees for a $40 purchase. Accepting Bitcoin seems like a great pitch to these businesses! Even if they billed the exact same price to customers, they could bypass the ATM fee for Bitcoin payments. For my purchase that would have saved almost 15%, and it'd save even more for smaller payments!
