A single purchase attempt. Never again.
Have only attempted to buy from them once - attempted being the keyword. For whatever reason, I was sent an email that was asking for personal details related to my PayPal, all in the name of security. Questions such as what city I live in, my full name, my email address of the account. Why don't I just give them my birthday while I'm at it to put myself at even greater risk of scams and theft. This is not standard practice for any of their competitors, and I'd rather shop with the knowledge that my personal details aren't willingly being shared over email.
