Wheelbarrow money in Venezuela

WSJ Reports  on big stacks of paper per purchase:

While use of credit cards and bank transfers is up, Venezuelans have to carry stacks of cash as many vendors try to avoid transaction fees. Dinner at a nice restaurant can cost a brick-size stack of bills. A cheese-stuffed corn cake—called an arepa—sells for nearly 1,000 bolivars, requiring 10 bills of the highest-denomination 100-bolivar bill, each worth less than 10 U.S. cents.

Rigid state price controls have only made matters worse, economists say, generating a thriving black market for just about every good, from car tires to baby diapers, in which cash is the preferred form of payment.
