If you haven't already started your online Christmas shopping this year, have no fear. WalletPop has already covered the deadline for sending packages to our troops overseas, as well as the dates for many retailers. We've also looked at the ins and outs behind Free Shipping Day, a day of guaranteed by Christmas free shipping, which takes place on December 18th.

In case you're too busy to order on these shipping dates, Dan de Grandpre and Dealnews.com has compiled a list of order deadlines on Last-Minute Tuesday for over 60 retailers.

Deadlines for Christmas Eve include:

• Apple -- Dec. 23 (11am PT)
• Best Buy -- Dec. 23 (11am ET)
• Discovery Channel Store -- Dec. 23 (2pm ET)
• Hammacher Schlemmer -- Dec. 23 (3pm ET)
• NBA Shop, NFL Store and Shop MLB -- Dec. 23 (11:59am ET)
• Newegg -- Dec. 23 (12:30pm PT)
• Victoria's Secret -- Dec. 23 (1pm ET)
• And many more!
  

These are great dates to keep in mind, but you can easily get by without them. Simply place your online gift orders right now.

Many retailers are already offering free shipping on minimum orders and for most items the prices won't drop low enough in the next two weeks to justify paying for overnight shipping on the 23rd. One of the only categories that may prove worth the wait are technology-related items such as HDTVs and netbooks. If your recipient is lucky enough to get one of these I'm sure they'll be willing to wait until you find the best deal; even if it doesn't come until after the holidays.
