I do most of my weekly grocery shopping at Sam's Club. I have 4 children so buying at Sam's is very smart for me. I purchase ground chuck at 1.59 per lb and can buy twice as much at Sams than at the grocery store for way less. 3 lbs of bagged salad is $2.99 and cheaper than grocery store, milk is over $1.00 per gallon cheaper, eggs are cheaper...frozen chicken....OH I can go on and on.
I spend WAY less and get more food at Sams than at the regular grocery store.
