What's wrong with AlertPay? They seem like a pretty honest business and I've never had any trouble with them, though I've only ever bought things, not sold them.
Other than that, it's a pretty solid service.
Nothing wrong with alertpay per-se that I'm aware of but fraud is rampant there.
This is to be taken with a grain of salt, but a search for 'paypal fraud' turns up 2 million results, about twice as much as alertpay, and given the relative size of the companies that's worrisome.
AlertPay charges 4.90% + 25c
WePay charges 3.5% (50c minimum)
(for credit card processing)
The dividing line (between the traditional macropayment and the micropayment) is supposed to be $12. The only drawback is that you have to run it from a different PayPal account.
For a $2 transaction, the macro works out to 30.058c fee, while the micro is 15c fee. For small stuff, it may be a better deal.
