4. Look up Deals Before Shopping

Don’t kid yourself, checking out discounts and sales while in the store won’t achieve much. You’re better off looking them up beforehand if you can. That way you can avoid being bombarded by unnecessary and unwanted sales. If you don’t, you’ll run the risk of buying stuff you don’t want, nor need, just because they’re cheap. 

It’s also acceptable to change your meal plan a little bit in order to take advantage of sales. Hey, if it’ll help you save a few bucks, why not?
