I was thinking of this thread and someone mentioning about buying 30 bins when I was at a garage sale this week. Sometimes I buy new totes when I have the money and when they're on sale. Lots of times I'll see them at garage sales - resale shops - or just repurpose ones I have around the house.
At a GS I saw a huge Christmas tree in a Rubbermaid tote with snapping lid ($$$ new). They only wanted $5.00 for the tree - I was thinking of buying it just for the tote! I didn't because I already bought a Singer sewing machine in a cabinet and didn't have any more room in my car! LOL
Keep your eyes open!
