Update:
Turns out that website, while still in existence, is no longer being used! Since it’d been a couple of months since I placed my small testing order, I figured I’d look into it. If it was a scam, I figured, well, it’s “only $30” down the drain. So, I was happy to see they had a phone number. I called and got a live person immediately. A potential win! I explained what’s happening and got a “Oh my goodness. That shouldn’t have happened.” Then he said “Oh! We stopped selling those. You shouldn’t even have been able to order those. That old website isn’t the current one.”
The new, working site is: https://www.square1masterpiece.com
He was kind enough to kill the shipping charge and throw in a few extra sheets of a similar product (that they do still make!) for my troubles. Nice guy. I’ll review the product sometime soon it looks like!
