It isn't for me. I would say I distrust Amazon as much as their bank (or vice versa).

Maybe I won't believe my bank won't give me access to my money tomorrow, or I won't believe Amazon will keep my money and won't send me the product I bought, but I know my bank try at all cost to introduce me to products that won't benefit me as much but would benefit them a lot, and I know Amazon would post Chinese knock-off products aside legit ones without any way to filter them.
