This is the formula:

1. Print your invitations on your computer.

2. On the invitations print 70% of them asking to bring hors
d'oeuvres.

3. Print 20% of them invitations asking to bring dessert.

4. Ask 10% to bring red or white wine.

5. Ask a few friends to bring paper plates, plasticware, and
napkins, these friends need to arrive 15 minutes early to set up.

6. You spend $50 maximum on drinks, iced tea and wine.

I've tried it and it actually works.
