Today only, Home Depot cuts 10% off retail prices sitewide via coupon code "JX84KHGT". Better yet, it stacks onto already-discounted sale items, yielding even greater savings. (If it's already discounted, the 10% off is subtracted from the pre-discount price.) It's the best sitewide coupon we've seen from Home Depot this year. Shipping starts at $6.64, or get free shipping on many orders of $45 or more. (In-store pickup is also available on many items.) Sales tax is added where applicable.
