DAF DISCUSSIONS - BAVA BASRA 90

Barry Epstein asked:

90a- The Rashbam says that one who buys from wholesalers and sells to individual customers is Rabbinically forbidden to mark it up by more than 1/6th. This applies only to staples. Then how do grocery stores today work, as they certainly buy staples from wholesalers and mark the items up by more than 1/6th?

The Kollel replies:

The prohibition was for retailers for whom the only difference was that the retailer sold it piecemeal rather than all at once.

Today, in contrast, the retailer has a myriad of costs, delivery, overhead, taxes, interest, etc., and all these are factored into the price (see Shulchan Aruch, Choshen Mishpat 231:20). Today the only prohibition is to sell over the market price, if such can be determined.
