It might be imagined that during a period of prolonged economic downturn, retailers would be doing everything they could to stop customers taking their business elsewhere. They would, for example, not take the risk of imposing excessive credit-card surcharges.
That, anyway, was a theory when, in 2009, retailers were given the go-ahead to pass on transaction fees to card users.
So much for theory. As the response to a story last week in this newspaper's ConsumerWatch section confirmed, many retailers are all too ready to impose surcharges far in excess of what banks charge them to process the transaction. For them, it has become a source of easy money.
The worst offenders are companies that enjoy market power and do much of their business online. Feedback to the Herald on Sunday places airlines, concert ticket sellers, parking companies, tourist operators and taxi companies at the top of this list.
While many retailers are happy to set their surcharge at an acceptable 1 to 3 per cent, the charges imposed by others range up to and beyond 10 per cent of an advertised price. In many cases, they are simply exploiting the dearth of practical payment alternatives to credit cards.
