The site is faulty at best, sketchy at worst
I tried 5 times to order a few items, with 3 different perfectly good credit cards. Each time I got some message, saying the payment failed or the payment method was "invalid" whatever that means. I tried contacting their support,and they basically said "Nope, that wasn't us you tyried to order from. Musts been someone else". Which is ludicrous because I got their email from the same page I tried to order from. I sent them a screenshot of my order attempt and they stopped responding. I think they're highly sus.
