After Ebay bought PAYPAL and discontinued its own payment service, I thought that left PAYPAL as the only payment service. I was poking around Ebay and found a seller with an icon from another payment service called Checkfree. Its claim to fame is that it's cheaper than PAYPAL (1.85% vs. 2.9%) and that it uses eBay's Authentication & Authorization Process for seller verification. Payment method seems to be simply money transfers from buyers bank account to sellers bank account; it appears that Checkfree does not allow buyers to use credit cards for purchases. That's a plus for some sellers, a minus for others. Is this a legitimate service? Anyone ever use Checkfree and have an opinion about them? I do not like the idea that they ask for your Social Security number.
