Hmm I might try that next time I'm buying wood. But I think they usually take out all the dinged up pieces...Every time I get mdf I hit up lowes and purposely look for a sheet with a dinged up corner . They always give me at least 25% off if I ask. I even got a whole sheet with maybe 2 inches that weren't useable for 7.50 once. Always get a discount when I ask at lowes .
