type of cloth, remember that stores change their product depending in the season and if your friend don't do it there is a problem, is like selling sweaters in summer of course this depends in the country right on my side is sun and beach, also don't have to much of all the products, always purchase a few and when he sees a premium clothes have more of those for the quality, also remove and add cloth from the catalog, the more options you give people the difficult is for them to choose so you give them 15 or 20 options not from 50, change 5 or 7 every two weeks to give the impresion that the cloth is selling and isn't catching dust because product is not moving.
