You probably know that the best time of year to get a great deal on certain items is immediately after they are no longer useful. This is because demand falls off a cliff. . . .
For example, flowers are pretty cheap on February 15.
Christmas cards go on sale after Christmas. So do decorations, sometimes.
If you want to buy a new lawnmower, don’t buy one when everybody else will also want to buy one: at the beginning of the grass-cutting season. Wait until everybody puts theirs away in the Fall and the stores need to start making room for their winter gear.
It would be great if someone came up with a chart to keep track of information like this.
As it turns out, they have.
The following link takes you to a page that contains a detailed, comprehensive chart on what items to buy during which month:

It also contains explanations for why each item is listed where it is. That way, you can use your own judgment to form different conclusions if you need to.
