I Will never order from them again, never got my order or a response to my emails!... this company have about almost 200 complains, I did report it to the Better Business Bureau, after I read all the complains!... Bad Company!

Never had a problem with mobstub and have ordered quite a few times. I don't see why you couldn't use your amazon card as long as it had the visa logo on it

I have no idea. I wouldn't order anything from them anyway. Never hot my products and my credit card was charged twice. No phone number to call and NOBODY has ever responded to my emails. That was in October of 2014. Buy from a more reputable sight!
