As such, those who wish to upgrade to the Galaxy S5 should consider trading in their old Galaxy S3 or S4. Having any of the two at its best condition will have a huge impact on the amount consumers have to pay for the Galaxy S5.
Consumers can snatch a $100 deal for the Galaxy S3 and $200 for the Galaxy S4. Selling the latter will reduce the cost of the Galaxy S5 to $0. After all, the Galaxy S5 is sold at $199 for two-years contract.
We do recommend trading in the old Galaxy device with Gazelle or Nextworth it actually offers a 30 day price lock. This is really important as once the S5 is on the shelves, prices of the older devices will be depreciated even further. Of course, those two companies are tied to an AT&T contract.
Here is the expected trade-in value of three major companies:
Gazelle: Galaxy S4 $187, Galaxy S3 $104
NextWorth: Galaxy S4 $134, Galaxy S3 $77
Glyde: Galaxy S4 $298, Galaxy S3 $218
The third company pays the best but it will consume a lot of time. Instead of getting a fix payour for the old smartphones, Glyde actually offers a service where it assists users to find a customer. Of course, the company will take a cut of it.
