Of course, by renting, consumers are paying an implicit interest rates to RAC, the company peddling the scheme. The price of renting a Sony 55" television is $29.99 a week. The cost of a Sony 55" is $1899 on Amazon. Let's say the expected life of a Sony is four years (it is probably longer). That is an implicit IRR of 1.51 percent per week, or 117 percent per year. There used to be a word for this kind of thing, and the word was usury.
This is different from legitimate rental businesses, that rent out equipment for short periods and that have to keep inventory that often sits idle. But to suggest to consumers that they are better off not using their 24 percent APR credit cards for this scheme--it is disgraceful.
