Retailers may be doling out in-store discounts, but when it comes to credit cards, they’re increasingly charging more, the Washington Post reported on Saturday. Interest rates on store cards, which have been inching up for years, now average about 25 percent, according to data from CreditCards.com, part of an online credit card marketplace. And, for the first time, at least one retail card commands a rate above 30 percent. A card offered by BrandSource, a network of locally owned appliance, electronics and home goods stores, comes with an interest rate of 30.49 percent. Three others — Big Lots, Piercing Pagoda and Zales — have rates of 29.99 percent.
