Compulsion to buy foods on sale, use coupons and eat them all

So I buy all my foods online since I have a chronic illness and can’t really go out much.

The main one I use is the grocery store website and I find myself buying foods on sale that week that I wouldn’t otherwise buy. When the foods arrive, I feel like i need to eat them all relatively quickly before they go bad.

My financial situation does not really warrant this. I could afford to buy regular priced items only but I’m frugal so I like buying stuff on sale.

I guess in the long run, it’s better I avoid the weekly deals pages all together. this way I might buy less stuff.

Also with Uber Eats. I feel like I HAVE TO buy TODAY to use the coupon that expires today.

Anyone relate to this?
