Ah, right, I guess Americans (I'm assuming you're one from what you typed) haven't experienced the ecommerce platforms of Asia. Basically check the store ratings, reviews, and then make a decision yourself. The platforms are usually good in stepping in when there's a dispute. I've had three no shows; the sole Aliexpress one did a refund, and the two Lazada ones (Lazada is another ecommerce platform) were automatically refunded!
