I see no 3rd party processing encryption certifications.
The website is built off a generic "do it yourself" type template.
I don't see any guarantees that legally promise you anything, in fact all I see is docs protecting them and saving them from responsibility.
There is no built in-stock inventory update that I can see.
I would not be shocked if they took your cash, waited three weeks to get back to you and then let you know an item is not in stock.
The good news is that most modern credit cards have your back for online purchases, it's just a PITA to get refunded that way.
