Edgars Somerset mall reselling worn goods on their shelf

On the 26th of May 2022, I went into Edgars Somerset Mall to take advantage of the 50% off Kelso boots sale. On the Shelf, there was a pair of boots that had been worn and returned to Edgars and in turn placed on the shelf to be sold again. When this was pointed out to them the response was very poor as the manager was supposedly not in the store, surely one gets an extra discount for worn goods?
