They aren't going out of business, they are simply taking the smartest move on the web today and canning Visa and MC's stupid asses and using ACH Debit which is the future of the web. No more chargebacks woooohoooo.
Keep your eye out, more will start dropping visa/mc and going to ACH Debit now that ach debit can be done instantly through ProBilling's directcheck feature
Will cut down on purchase fraud quite a bit as well, I find it a very smart move indeed, way to go probilling;)
