Paypal not accepted because any company who very sneakily slips into an "update" to existing members and then very AGGRESSIVELY lets you know you just signed (after its too late) a policy that so specifically disallows you from participating in any class action suit on any level is a company that ANTICIPATES a LIKELIHOOD of this becoming a WIDESPREAD FUTURE concern (Class Action Suit = 100s or 1000s of litigants usually) - even based on their own perceptions of how they intend to conduct business, Are CROOKS.
Implementing that Policy basically implies that they PLAN to shortchange/defraud and otherwise aggravate a substantial number of customers to the point of their pursuing litigation (which only about 1/20 legitimate FRAUD victims actually do, so multiply the anticipated litigants by 20 and there's the damage) and they are securing the success of their fraud scheme by eliminating your only likely means of recourse - as I'm sure no single private seller could afford a fleet of lawyers to match paypal's army (hence eliminating class action)...UGH Why set yourself up to be ripped off? Writing's on the walll!
