I recently returned a couple electronic items, including a HDMI-to-VGA adaptor, that I hoped to use to feed an old Video projector, to a Walmart store, because I accidently bought the wrong items. (In the case of the cable, it lacked an audio output. It also didn't support conversion of 1080p resolution video to the 1024*768 mode the projector wanted, though it worked at lower resolutions.) I had cut the shrink wrap packaging open to try the cable, so I wasn't sure they would accept it. They did. They didn't ask for my reason, or whether the items worked. There was no restocking fee.
They seem to have a pretty good return policy
. With a receipt, within the return period, you can freely return most things.
I haven't tried this on special orders. But that website says "Return items by mail or in store... Ship it back for free. It's as easy as logging in to your account & printing a return label."
, it also says the same policy does not apply to Walmart Marketplace (items not sold and shipped by Walmart.com), so you might avoid those things, if you may need to return them:
Of course you may have to pay a little more than if you buy things through the cheapest eBay or Amazon marketplace merchant, and Walmart doesn't carry everything, not even on special order. But they do have have a few extenders:
(Note that some of them ARE from other other merchants, and would not carry the good return policy.)
P.S. My opinion: It's one thing to return something because it's no good, or doesn't work they way you hoped. But taking unfair advantage of such a policy in other ways could mess things up for the rest of us. So I suggest you don't over-use it.
