The trade-in market is starting to flourish once again as the upcoming arrival of iPhone 6 draws nearer.

Over the years, the trend for iPhone product trade-in deals surged since the consumers would want to have the means to get their hands on the latest Apple gadget as soon as it was released in the market. 

Now iPhone lovers are given more options to trade their old iPhone devices to get the brandnew iPhone 6. They just have to choose the best one that could offer the most value for their old phones. 

One of them is Gazelle, which promises that an iPhone will be exchanged for cash in just a few minutes. Gazelle offers a very tempting price-lock deal if the iPhone user would decide to sell it during the week of September 9.  

Gazelle offers as high as $335 for both the unlocked and Verizon-locked iPhone 5s 64GB, while the network-locked iPhone 5s 32GB units can be exchanged for $285.

Verizon also provides a decent deal for those who want to upgrade their old Apple phones to the latest model and sign a new contract with the network provider for two-years. But instead of cash, Verizon will offer a $200 gift card which can be used to purchase the iPhone 6 16GB unit for $199.99.    

On the other hand, iPhone users who are aiming to get the most money out of their old devices can try putting up their old devices for sale in Glyde. This service promises to sell the old devices in a real peer-to-peer marketplace setting, which could allow the users to set up their own price. However, there are no guarantees that the device could be sold immediately. 

Other popular websites like Ebay and Amazon have the same policy when trading-in an Apple phone. But Amazon also would also offer a gift card that can be used in their website instead of exchanging the device for cash.

In addition, Apple is now offering a decent trade-in value so that their loyal customers can upgrade the old devices for the brands latest product as long as the money that they will acquire from the deal will be used in exchange for an item in the Apple Store. For example, the iPhone 5 that could be worth $185 in other trade-in deals could go as high as $225 at Apple. 

iPhone 6 is expected to be released in the market in the next two weeks.
