Best Buy

A leaked internal document obtained by TechnoBuffalo reveals that Best Buy is preparing to roll out another iPhone trade-in program. According to the image posted below, Best Buy will offer a minimum of $100 in credit to customers who trade-in select smartphones. The smartphones have to be in working condition, and the credit must be used to purchase a new iPhone 5s or iPhone 5c. The promotion will run from October 13 to October 19 and will only be available at select participating locations. Previously Best Buy was offering $50 in credit to anyone who purchased an iPhone 5c, without having to trade-in an older device.

As you may already know, $100 isn't really a great deal for a used iPhone. Electronics resellers such as NextWorth and Gazelle offer much more money for older Apple products. You can compare iPhone trade-in prices using our table here.

Well that didn't take long. Best Buy is already offering the iPhone 5c for only $50. Customers who buy the new Apple handset from the electronics retailer will receive a $50 gift card with their purchase. Best Buy is also offering the same deal on Samsung Galaxy smartphones, including the Galaxy S 4.

This is the next best deal after Sprint's free iPhone offer, but you have to be willing to switch carriers to take advantage of Sprint's discount. Both Target and Walmart are selling the iPhone 5c for $80, meaning Best Buy does currently have best deal on Apple's "unapologetically plastic" handset.

Looking for a deal on the soon-to-be obsolete iPhone 5? Best Buy is running a special over Labor Day weekend for those looking to trade in a working iPhone 4 or iPhone 4S. Besides taking your old iPhone, Best Buy will ask for your signature on a two-year service contract with AT&T, Sprint or Verizon. In exchange, the iPhone 5 can be had for half price.

That's right, a full 50% off on both the 16GB or 32GB iPhone 5, brand new. This equates to $100 savings on the 16GB model and $150 savings on the 32GB iPhone 5. CNET explains that the deal is good from Friday August 30 until Monday September 2, 2013. Of course, your old iPhone must not be water damaged or have a busted display.

Four weeks. That's how long the latest Best Buy iPhone sale will go on once it starts on Sunday, May 26. So what is the store offering to new customers who sign a two-year contract? No less than $50 off every iPhone 4, iPhone 4S, or iPhone 5 purchased during the sale period.

The great news is the $50 off deal applies to your choice of three different wireless carriers, AT&T, Sprint or Verizon. According to AllThingsD, Best Buy is also offering discounts on several Android smartphones for one week from Sunday May 26 to Saturday June 1. Unlike these deals, the sale on all iPhone models will continue until June 22.

Sometimes a promotion comes around that sounds too good to be true. If you're one of the millions of Americans who still has some last-minute holiday shopping to get done, there's a gift card deal ending today, Saturday December 22. Best Buy is selling iTunes gift cards at 20 percent off face value.

The discount applies to Apple iTunes gift cards purchased in Best Buy stores at denominations of anywhere from $15 to $100. The recipient can redeem the iTunes gift card for apps, books, movies, music and television shows and even spend the money on the Mac App Store.
