I do the same at Lowes. They do (or did have) lockout on returns but I never found the conditions. Since lowes went to their mylowes card and automated receipts, I haven't been stopped from returns (unless the initial purchase didn't get logged to my account. Then, without a receipt, they often times don't accept the return.)I do this at my Lowes. Who wants to run back and forth to the store for a few misc. items. I'm not a contractor but I spend lots of money there. Stupid policy on HD's part. Hopefullythe guy calls corprate to straighten that out.
