To lessen your burden:
during the salmonella scare along with the Turkey Week the ground beef was sitting in bulk (didn't even turn brown yet) so EARLIEST MORNING HOURS USUALLY WED midweek Walmart reduced to sell packages of ground beef something like only $2.38 for the pound packages, you look for those opps and buy a bunch seperate useable portions and freeze (a no brainer). Same thing with pies and over baked racks under $3.00 many 50% off. When no sale on ground meat, the frozen 1lb blocks are under $4.00 at the open frozen bins with those packages of tasteless preformed hamburger patties, also there is frozen ground Turkey, it was under $2.00 during Thanksgiving for many obvious reasons and always under $3.
During holidays where Ham is served the other pork portions are abundant thus reduced, Smithfield sells Flintstone size rib racks for $9-$12
Walmart London broils or prime cut tender chuck roast under $10, can be cut up in the more tender portions and tenderized as steaks (as tender as a NY stk if done right), while other portions of the roasts portioned into cut blocks and frozen to thin slice steak sandwiches, fajitas, stirfry, or preassure cooked for string pulled beef for burritos and barbeque beef. At the back deli of Super Walmarts are bins of packaged meals sometimes reduced to sell in early mornings, 5-6 Huge Shrimp Pene pasta under $3.00, Terryaki Chicken thighs reduced under $3.70 & where the potato salad beside the deli is day old rotisserre chicken sometimes reduced $2.68-$3.98 depending on when.
Rollback bags of chips under $2.
Store brand sodas $1.
Tomato for hoagies and hamburgers the trick is buy the seperate romano tomatoes weight wise a nice fat size one only cost $.29 each, cuts waste on those rotting second and third tomatoes in the package. To make your lettuce onion and tomatoes last longer the trick is using wax paper(absorbs moisture and seals off air) on the cut part before celephaning and small zip locking them in a storage bag.
Besides clearing out items the morning shopping avoids annoying crowds and people touching everything with their snot nose & spittle hands, (important in winter cold season), no lines, close parking, safer easier experience.
*another good time is an hour or 2 before close they try to get rid of stuff especially on Sat and Sunday nights.
