davidcyclebackEven if sellers have preferred special ways to pay (auction helper,
PayPal button on website, etc), I doubt many would have a problem
with the buyer going to the PayPal site and paying from there.
The other thing is, after paying, you can go directly to PayPal.com. If the
payment is listed there, you were dealing with PayPal. It should register right
away.
