Each week you can get different sales, free shipping offers, financing deals, and exclusives on BestBuy.com. This week Best Buy has a ton of marked-down items in categories such as Cameras & Camcorders, Home Theater, and Car & GPS. I'm going to focus on four products in these categories: a 12-megapixel Samsung digital camera, a Pure Digital pocket camcorder, a Garmin GPS, and a Sony Bravia HDTV.

Find out the deals you'll want to grab and the ones you'll want to avoid, after the jump.

Samsung 12.2-Megapixel TL100 Digital Camera
(Regularly $229.99; Now $199.99)--Good Deal!
Best Buy has this 12MP point-and-shooter on sale for the week. It features a 3x optical zoom, a 2.7-inch LCD screen, face dectection technology, and dual image stabilization. It runs on a lithium ion battery and comes in four colors: red, black, blue, and silver. At $30 off with free shipping, it's gotta be a good deal, right? Yeppers! In fact, it's the only deal.

Pure Digital Flip Ultra
(Regularly $149.99; Now $129.99)--So-So Deal!
Pure Digital's series of pocket camcorders have earned average ratings of 3 out of 5 stars by PCMag's Brian Heater; great scores for such a lightweight and stylish, easy-to-use camcorder. The Flip Ultra model offers 4GB of internal memory, a 2-inch LCD screen, and four color options. At $129.99, you won't get free shipping with this deal; so if you're not picking it up in-store, you'll have to pay about $5 for shipping. But can you get a better deal elsewhere? You betcha. Both NewEgg.com and Amazon.com are offering the Flip for $129 with free shipping.

Garmin nüvi 255W GPS
(Regularly $199.99; Now $179.99)--Bad Deal!
Thank goodness for free shipping! Garmin's 255W sports a 4.3-inch touch screen, turn-by-turn voice prompts, a speed limit indicator, automatic rerouting, and preloaded maps of North America. This is already such a great deal, so why bother looking elsewhere? Because you always should, folks! Glad thing I looked, because Amazon has the 255W for $174.34 with free shipping. Score!

Sony Bravia KDL-46Z5100
(Regularly $2,399.99; Now $1,799.99)--Good Deal!
In the market for an HDTV? Sony's Bravia KDL-46Z5100, which earned four out of five stars by PCMag.com, is $600 off the regular price. This energy-efficient 46-inch HDTV feature 240-Hz display technology, an excellent picture contrast, and Internet and network multimedia streaming. Not only do you get free shipping for this set, but hook-up and recycling of your TV is included. This deal can also be had for the same price (with free shipping) on Amazon.com, so take your pick. Good deal verified.
