I find that the quality of lumber at Lowes is superior to Dumbyards. The 8x16 deck I put on the front of the house last year has only 6 or 7 knots in it. I do not got to Lowes shopping for groceries. I bought a Carbon water filter at Lowes for 32 bucks yesterday less my every day military discount which ends up more than Dumbyards discount. The same type of filter would have cost me over $50.00 at Dumbyards. The cheaper filter lasts the same amount of time as the over priced one.
