Start shopping sales now for things you'll need. Broth, flour, spices, etc. are all shelf-stable and buying a little each week won't be such a hit on the wallet. For turkey, keep an eye out for sales (my stores usually have them for $.49/lb), or you can always go non-traditional (I've made lasagna/stew/stir-fry). Also, I know each family has their favorite dish, but do not feel you have to serve every single one of them, especially if you are the one hosting. You don't need three potato dishes, four stuffings, etc. just make one.
