I want to surprise my friends!

I want to surprise my girlfriends on a budget, any recommendations as to what I could do?

We usually indulge in cheap vodka mixed with random carton juices (pineapple, cranberry, etc), with crisps and wafers on the side, but I want to try something new that they would love.

For context they hate creamy alcohol mixes, or anything that is too risky. Please let me know if you guys have any ideas as to what I could prepare😭😭!!
