boutique , buy at 50 , sell at 600 . target mid income market -- buy at 10 , sell at 35. . to cover outfits been stolen , admin fees , sales person commissions ..... later , those you can't sell , is going to be a 50% sales , to clear stock , 70% , so do concern and think carefully . but some items you can mark up less than that , sell it cheaper to attract people in , to buy your normal items. good luck
