Anywhere to get Ubereats promo codes?

Uber Eats went from being my most used takeaway app, to never being used again app

I keep getting emails ,but when I don't know the delivery costs and which takeaway I can order from I haven't used them, also I think you can't use it for pickup it's delivery only, is that correct.

Always sending me codes that dont work, so have given up on them

I think you can apply a code (if you can get one to work) and choose pick up option

Prices for curries etc are now so stupidly high, that I expect a lot of places are getting no customers anyway. A lot will go bust
