First, a bit of background. The fee in question is widely described as a "checkout fee," and starting on Jan. 27, retailers will have the option of charging it on any purchase made with a credit card. The fee came about as a result of a settlement reached in July 2012 between merchants and credit card networks, and is intended to help defray the costs of the swipe fees charged by those networks. As such, it can't be higher than what the merchant actually pays as a swipe fee -- usually between 1.5% and 3% of the transaction.
The settlement was actually merchants' second swipe-fee victory in recent years. The first came in the form of the Durbin Amendment, which capped swipe fees on debit card purchases at 21 cents per transaction. The July settlement didn't cap swipe fees on credit cards, but it did give retailers the right to pass them on to consumers -- if they choose to.
"I don't think we're going to see a mass amount of surcharges come the deadline," said Ruth Susswein of Consumer Action, which has led the charge in educating consumers about the impending fee. Retailers, she says, are more likely to introduce the fee gradually. "It might creep into costs of shopping over time."
Indeed, it's still unclear whether the nation's larger merchants actually plan to take advantage of their new right to add surcharges.
So if you do see checkout fees, it's more likely to be at smaller retailers, which tend not to be winning on price anyway. In fact, Ulzheimer noted, you've probably already seen small merchants charge a form of credit card checkout fee in the past, by offering lower prices to customers paying with cash -- for instance, at a gas station. Now that they're allowed to call the credit card surcharge what it is, more small merchants will try out variable pricing.
Tens of millions of customers will never see checkout fees, though. That's because 10 states have formally banned the practice, a list that includes California, New York, Florida and Texas.
If you don't live in one of those 10 states, though, you could potentially see signs alerting you about checkout fees as early as this Sunday. If you do, you can avoid them by paying with cash or a debit card -- or by taking your business elsewhere.
