Sam’s Club: 2lbs of almonds for $13, raw and unsalted. Also delicious. They have a bag of walnuts too.
Sam’s club also has protein powder of questionable quality, but it seems to work okay for now. For me at least. It was cheap, but Grow! Whey on here is the same price for a 5lbs. tub. Just order a bunch at once to save for shipping charges.
Don’t forget Sams has 6.5lbs boneless/skinless chicken breast for $14 and 3lb bags of precut broccoli and/or mixed veggies for $5. Both part of my weekly shopping list.
I tend to just buy a few bunches of broccoli at around 1.50-2.00USD per bunch. Then cut it up. A few bags of frozen green beans, a bunch of celery, and a few green peppers are usually my weekly veggie list. Comes to around $10.
To the OP:
It’s important to shop around. Having worked in a grocery store for 5+ years now, I can tell you that some places just suck to buy things at. But then there’s places that have good deals. Smaller chain stores tend to have better produce prices and higher quality meat at the same price as bigger chains.
Shop around. Go to grocery store one week and see what your bill is, then try someplace else. Stick with the place that’s cheaper (obviously). I also tend to look at the weekly add when making my menu. If something tasty and healthy (ala turkey sausages or brats) are on sale, I’ll put that in my menu for the week. See what the deals are, and buy more one week and save it for a while. This means the grocery bill will change from week to week, but it pretty much balances out in the long run.
