Gazelle offers 10% sales bonus as Verizon iPhone incentive
Gazelle is offering a 10% bonus to the first 5000 people who sell them any used cell or Smartphone before Sunday, Feb. 6. They're offering this is an incentive to those who are planning to upgrade to the Verizon iPhone 4. Just use bonus code VZW5000 at checkout and you'll get an additional 10% for your sale (if you're among the first 5000).
If you aren't familiar with Gazelle, they pay cash for various electronics based on popularity and condition. They then refurbish the items for resale in different markets.
When the iPhone 4 came out we sold my son's 3GS through Gazelle and received more for it than we would have through eBay. The transaction was fast and smooth and when they received it, Gazelle felt we had graded its condition too low so they paid us more for it than we originally expected. You can't ask for much more for that.
If you have some old electronics to sell, give them a try.
