Cookware & Kitchen Accessories: Holiday deals start pretty early, and cookware is one of the more popular items that you'll find on sale all quarter. [Bankrate, Dealnews]

Plants: If you have a cellar or other area that can store plants until the spring, you can pick them up now pretty cheaply. [Real Simple, Dealnews]
Toys & Games: Again, the Christmas sales start early at places like Toys R Us, and will continue through most of the holiday season. The closer you get to the holidays, the better the deals...but also the more stressful it becomes (we've all seen Jingle All the Way, right?) [Dealnews]
Wedding Supplies: Winter's back, which means finding a venue and negotiating those services is going to be a lot easier. The deeper into winter you get, the better the savings. [Bankrate, Dealnews]

Televisions & Other Electronics: The sales continue after Black Friday and Cyber Monday, usually all the way up until the super bowl. [CNET, Di Vincenzo, Dealnews]

General Buying Tips for Any Time of Year
Apart from the above time periods, there are other days of the week or year that are best for buying certain items (which is great if you can't wait three months for a new computer). We've mentioned a few of these around the site before, but in the interest of being comprehensive, here are some things to keep in mind:
Appliances tend to be cheap on Sundays, when most people are out buying new ones. In addition, you're bound to find great deals on any major holiday, like Memorial Day or Independence day.
Computers & other electronics are cheapest on Mondays, when manufacturers apply their rebates. This applies to TVs, cameras, and video games as well.
Entertainment venues like museums and amusement parks often have discounts during the middle of the week, when they're less crowded. Plus, smaller crowds are always nice. Some museums might even have free admission days, so check out the venues you're interested in for more.
Gas prices are higher on the weekends, hitting their peak mid-morning on Thursday to anticipate all the weekend drivers and travelers. Fill up on Wednesdays or early morning Thursdays for the biggest savings.
Jewelry is best bought on Wednesdays, when most people tend to shop for it. However, stay away from gift giving months like Valentine's Day, Mother's Day, and Christmas.
Chocolate is great to buy after any holiday that involves chocolate: Halloween, Christmas, Easter, and Valentines's Day, for example. They'll be clearing out all their holiday-themed candy, so you can grab them up if your kids already ate their chocolate rabbits and Santas.
And with all things, if you find an item you like, monitor it regularly. Things go on sale for no reason all the time, whether it's a Shell Shocker on Newegg, the end of a clothing season, or when a particular product goes through a refresh (like Apple computers).
That's our big list for the year. We'll be updating you at the beginning of each month, reminding you of the best things to buy, but this should help you plan for the year ahead. Good luck!
