Do the same thing purchase fabric, then repurchase it 3 or 4 months later. Quilt books I think I must have 7 or 8 duplicates. I do believe that I have 5 sets of the tri-rec rulers. I could go on and on but then I would have to go thru my sewing room and would find a whole lote more. The nice thing about this is that someday you won't needd anything///
