That's probably where the Smithing Stones come in. Chances are you can either buy a regular weapon new from the shop at its fixed price, or repair a weapon you already have at a discounted price in addition to those Smithing Stones.
Those Smithing Stones would have to be used to repair your better, rarer, and PRF weapons as well, so you decide whether to just keep buying stuff straight from the shop to save the Stones for your special weapons, or keep repairing everything that breaks so you're not stuck using your rarer weapons when you want to save them for later.
