Cheap food for a party I am having?

I am having a Girl's Night In adult relationship enhancement party at my house in a few days and I have to provide snacks and drinks. I am on a small budget here and trying to spend as least money as possible. What are some ideas for snacks that I can have???? I was thinking of a fruit and veggie tray and maybe chips and dip but, that's all I can think of. ALSO--> I was going to serve some type of alcoholic beverage to maybe loosen people up and make them feel more comfortable but, wasn't sure what type to serve. I need something that lots of ladies like, but still isn't alot of money. I was thinking of Hunch Punch but, that contains lots of kinds of alcohol which means it could get pricey. What about margaritas?? I just need some cheap ideas. Thanks in advance!!
