Do you seem to not have enough money around the season of Christmas? I know what you mean. However, if you start doing a little shopping here and there this summer, you can accomplish it!
Here are a few tips:
Make clean-up easy!
Go to your dollar store for those little items that are appreciated.
Does your family have special baked goods that are shared every Christmas? Make sure there are enough to go around!
Take Home Leftovers Containers
Do you always have tons of leftovers at Christmas?

Grab your coupons and buy those canned green beans, mushrooms, corn, fruit, spaghetti sauce, etc.
My roommates and I do not use fine china. We bring out the paper plates so as to have an easy clean up.
Bring out the coupons for spaghetti (if you do not consume homemade), mashed potatoes (if you do not consume homemade), etc.
If the cost is good, buy a little here and there and stuff your freezer.

I highlighted mostly the gathering at dinner most take part in as part of the season of Christmas to buy for. I do not take such gatherings for granted as there are people who cannot.
One last tip:
Merry Christmas!
