Inquiry (采购产品): Defect I have a light fixture that uses four of your 2' x 4' sheets. Last week I bought four sheets at Home Depot. The bar code on my receipt is 074507992151. They cost $8.56 each. I have used your products before on this same fixture with no problem, but this time each sheet sags, causing the edges to rise up. If I go through the trouble of taking them down again, Home Depot will exchange them, but will that help? What is the problem with these sheets? For example, are these discontinued sheets that are too old? **** Hidden Message ***** Marvin Lustiger 85250 Company: none E-mail: mlustiger@juno.com **** Hidden Message ***** mlustiger@juno.com
