A holiday dinner for the whole family is a massive task that gets pricey fast. You want to focus on the memories, not the sticker shock at the checkout line when you are buying food for a dozen people.
The secret is timing your buying to avoid the holiday price spikes. Most of these ingredients can be bought weeks early if you have the freezer space, which keeps your bank account steady while you prepare.
Remember that the 0% window is a deadline, not a gift. If you still have a balance after the 18 months are up, the bank will start charging you interest on whatever is left over.
