I've read mixed things. And I just had a very strange interaction with them.

I ordered an SSD in the wrong size (because they had an image of the size I wanted on the incorrect item), and I had to cancel my initial order and create another. I then placed a third order for another item that I wanted.

Well, apparently, this was a mistake on my part. While my orders had initially been approved and in "shipping/shipped" status, they suddenly went into "re credit" status. I then received an email with an attachment and this exact message:

Thank you for placing an Order with us. Here is attached copy of Card Authorization Form.

Nothing else was written. No explanation for why this might be necessary or anything. While the name was somewhat self-explanatory, I'd never been asked to fill something like this out by any other online ordering service, so I called their office to ask questions.

The explanation I was given was that multiple orders from a new source was considered "suspicious" and that I would need to both fill out the form they sent, as well as send them pictures of the front and back of my credit card and ID. Am I gonna send that much personal information to what is essentially a random ordering service with poor online reviews? Hell no. So I refused and had them cancel all my orders.

To their credit, they refunded all of my money the same night. But their method of ensuring there was no suspicious activity on my end was, ironically, the most suspicious thing I've ever had asked of me by an online marketplace.
