This is pretty well only for merchants who do some or all of their selling with PayPal.
PayPal's redesign 6 -months ago (??) now makes it less than simple for a user to figure out how to pay you by credit card without being forced to either create a new PP account or login to their existing PP account.
For the time being, I put up this quick and dirty walk through that I'm thinking of linking to (or having open in an ajax popup). I'll have my grpahics guy actually make it pretty.
But ... for PayPal merchants... thoughts?? Do you feel this helps the sales process or hinders it?
