The electronics retailer is offering this opportunity to iPhone owners over the Labor Day weekend.

Best Buy ran a new promotion over the weekend that allowed the owners of certain Apple gadgets to be able to bring in their old version of the iPhone devices in order to take part in a trade-in that would allow them to purchase the current version of the device, the iPhone 5.

The event ran for the length of the holiday weekend and gave a considerable discount on the current Apple device.

The electronics retailer offered people who brought in their old iOS gadgets the opportunity to purchase the current iPhone 5 – in either the 16 GB or 32 GB version – at a discount of 50 percent. It was focused specifically at individuals trading in their functional iPhone 4 or their iPhone 4S.

This gadget trade-in trend is growing among retailers and has been over the last few months.

Gadgets trade-in promotion - Best BuyThe reason that gadgets retailers are promoting the current iPhone 5 with massive discounts through old iPhone or other devices is that it is expected that the next version of the Apple smartphone will soon be released, and they are hoping to clear the older version of the product off their shelves before that happens. This type of promotion is starting to happen quite routinely as some of the leading manufacturers release upgrades to their previous generations of devices.

It has also been suggested that Apple, itself, has certain programs up its sleeve to encourage the exchange of old gadgets for their latest devices. For example, they have already created programs through carrier partners such as T-Mobile, AT&T, and Verizon Communications. However, it is also expected to begin an in-store program that would allow consumers to trade in their old iOS devices so that they would be able to obtain a discount when it comes time to purchasing a newer model.

The latest rumors are suggesting that Apple will be unveiling both an iPhone 5S, as well as an iPhone 5C, on September 10, 2013. The speculations about the new device are soaring and have already even suggested that T-Mobile and AT&T employees have been told that they will not be allowed vacation time during the time on and surrounding September 20, suggesting that that may be the weekend in which the products will be officially launched.
