I've never heard of the salvage grocery store before, but I shop at Aldi and save tons of money every month feeding a family of 5. You have to bring your own bags and a quarter to get a cart (you get your quarter back when you return it) Their food is very good and extremely cheep. Check it out, there is one at 16 and Dequindre I believe. Good luck!
