I'm glad I got another 20Mhs hashlet today just before they increased the price.

Purchasing with credit card is slower due to the nature of the product and several verification steps they have to go through. For example, they(shopify I presume) didn't like the email address I was using and asked for another one. Give them your main email address. Preferably something with your real name in it. i.e. johndoe@gmail.com. And update your street address with the one you have on file with your bank. After doing that, my order was processed in about 6 hours. Non-USA Visa. Should still be faster in work days though. That was today, Sunday.

It is frustrating to wait longer and to be seen suspicious but I also know they have all the right to take things seriously in order to protect their business with all the increased fraud especially with digital goods.

Currently you can't order via a non-USA CC in zenminer.com but you can in gawminers.com. I'm sure this is going to be fixed soon though.
