What am I supposed to do? There are no more sales!?

Go to a food bank in your area.  You will get boxes of food that are nutritious.  It may not be what you crave (such as sodas), but you can learn to live without those.  Drink water instead of tea or colas.  Look for food that is reduced because the expiration date is close.  Buy it and freeze it.  It will still be good, and it will stretch your budget a little more.  A last resort (and I mean a LAST one) would be dumpster diving.  Find out when a store is getting rid of fruits and veggies that are not spoiled, but too ripe to sell.  Go there at night and load up.

Don't waste you money on soda for one.

The closures of plants are just hitting the retail market, due to corona. Ground beef near me is $8 per pound.

No advice bro, its the same over here in dear old Blighty. EVERYTHINGS GONE UP, we're being RIP OFF. 

I know what you mean! You'll have to get creative if you can. Try to find some online coupons to use, go to a Dollar Store if one is in your area, even go to a food bank to get some basics now and then. You might have to try some alternative foods or drinks for a while (tea or flavored water instead of soda, bagged rice instead of Rice A Roni, etc.). I look at it this way: I'll appreciate the stuff I used to buy even more after this! 

Also once your home made tea with lemon juice squeezed in it is cold put it in the fridge so it's ice cold or add ice cubes.

Sue the hell out of some people

You should shop more efficiently, and for different food. Soda is always an expensive option. So is canned or instant ice tea. 

Tea bags make ice tea too, by simply putting a few of them into a gallon of water in a large jar or container and leaving it SIT for an hour or two (Cold brew method.) You can wean yourself off soda--drink water instead. Not bottled water, TAP water. Soda is terrible for you anyway--it would be to your health benefit to stop drinking it altogether. 

For olive oil, there ARE cheaper brands--you have to compare prices. 

And comparing prices for everything you buy ought to be a habit. There are also cheaper grocers. Look around in your neighborhood for those that offer less expensive food. 

I know this all sounds easy--and maybe it's not easy for you to do this--but saving money on food is not difficult. You simply have to stop buying out of habit, and start looking for the deals elsewhere. 

Drink water instead of soda

1.  Learn to drink water. It’s free. If you want, you can add lime or lemon zest to give it some flavor.

2.  Use corn oil or a cheaper oil. 

3.  Buy tea leaves. You only need a few leaves to make a cup of tea.
