Yup, that was my only saving grace using the credit card, I usually just use Paypal. I guess either would of been OK but my credit card company stopped it before it was even authorized.
Checking online was the first thing we did after I received my credit card warning. Only thing out of our ordinary was literally just MassDrop. Not saying it is them, maybe I am just pissed but when I inquire even more, the location was Brisbane, California (right outside of SF). The location is what bugs me. BTW i'm on the other coast.
