What not to buy in December
Yes, calendars make great gifts -- especially for co-workers or people you don't know all that well. But unless you really have to have them (for gifts or yourself), you can save a bundle if you wait.
Expect better deals: Pick up calendars in February, and "you can save up to 75 percent," says Mendelsohn. "So it's really worth it not to buy them."
The trade-off is that you won't have the selection you would have had before Jan. 1.
What is on sale: Baking supplies are on sale.
From flour to spices to baking powder, the cheapest time of the entire year to buy is in December, says Teri Gault, co-author of "Shop Smart, Save More" and CEO of TheGroceryGame.com.
"You'll save half or more," she says. "And if you use a coupon, it can be 60 (percent off), 70 percent off or free."
