Apparently, the price difference compared to several other buyers was significant... in the hundreds of dollars. In addition, the transaction was handled smoothly. I haven't used them myself, as I tend to keep my equipment a long time. I have seven Macs, two iPads, and three iPhones in my household! But when I decide to let go of some of the equipment, ill definitely check out SellYourMac.com.
I've actually met their founders at CES and MacWorld shows and they are a motivated group of Apple enthusiasts. They claim to offer better prices than Gazelle and other big spending vendors who might have to make back that advertising revenue through less generous prices. Because they specialize in Apple, they know the real value of your gear, and their website offers lots of advice for Apple users.
The good news is you can quickly find out what they will pay you for your Mac and iPhone gear by visiting www.SellYourMac.com and decide for yourself. In fact, they have a vast array of iOS apps including one that will give you an instant quote, so that makes it really easy!
Hopefully, you'll be as happy as that associate who couldn't stop raving abut his experience.
