Since Halloween is in October, I thought this would be a timely suggestion. When you carve your pumpkin this year, bake it and puree it before it starts to rot. We have started carving our pumpkin very close to Halloween and usually on the next day I will cook it, puree it and freeze what I can't use right away. You could also cook it and just cut in chunks for whatever you want to use it for. There is a special pumpkin to use for pies, but we have found that our Halloween pumpkin works just fine for lots of recipes:
Pumpkin cinnamon rolls
And the list goes on... Today I am going to try pumpkin biscotti. I haven't ever made it before, but now is a good time to try!
This may not save you a lot of money, but there have been years when canned pumpkin was a bit hard to find and where prices have increased. It is more eco-friendly as well.
