I have one question, and one comment.
1. Why? seriously..just wondering.
2. I am against supporting Walmart. I know that this is borderline political, but I have to say...walmart killed small town america. Amongst other forces...but I wouldnt shop there, at gunpoint.
Just my 2 cents, I will get off my soap box now...and sorry, I understand your thread is interesting, but there are so many American companies you could spend your hard earned money with.
As for why, ( even though I'm not doing this I do have a good reason for it to be done) I think this is a great idea because we have a lot of younger members who can't afford custom knives ( I only have two customs because they were given to me through great threads on this site) and things like pelican boxes etc. However, if they see someone do this and realize the potential of items at their local walmart then perhaps they can go get items a little at a time and they can start to learn with cheap stuff until they can afford the nice gear.
As for ideas of items.
My local wal mart has
waterproof bag set (3) for 10 bucks
fatwood ( I think 10lbs for about 8 bucks)
Jute twine ( <2 bucks)
fox 40 whistles ( not sure of price)
space blankets ( 1.98 I think)
coleman firestarters that strike on box ( 3 bucks)
cotton balls
Petroleum Jelly
Hand sanitizer
Unlubricated condoms
bic lighters
magnesium firestarter blocks
clear plastic waterproof cases
ziploc bags
canteens
knives ( I got a buck medium stockman for 10 bucks, not to mention filet and kitchen knives all very cheap)
ponchos
first aid kits
folding saws ( I got mine from there for less than 10 bucks and it's worked for me for 2+ yrs)
hatchets
Choke tube pouch ( about 6 bucks makes an excellent get back kit to go on a belt)
Compass ( not the best in the world but surely better than nothing)
I've listed so much I'm not sure what I've missed but I think this is a great idea and I applaud you for doing it.
