The major problem I have with amazon is that there are a ton of counterfeit items so you are not always sure you are getting the real thing when it matters. But it's pretty convenient for everyday stuff - saved a lot of trips to the store so I'm not ready to give it up yet.

As far as Walmart goes, it's never a pleasant experience shopping there for me so I only occasionally order oil from there for delivery. They have a 90 day return policy but it's not very fun to actually return something there - it's not costco.
