Welcome to the PalmSounds Store
Here you'll find links to hardware from a variety of retailers of mobile music (and regular music) hardware. You'll also find links to stuff on eBay which you can't buy new anymore.

iPhones and iPod Touches:
The obvious thing to do if you want an iPhone or iPod Touch is to go to Apple, but sometimes if you don't need the most up to date device you could try getting a 2nd hand Touch on eBay, or try Amazon for slightly cheaper deals. Here are some links to help:
For the iPad the story is basically the same, so again a couple of links to help you find the best deal for what you need.

General Music Hardware links:
If you're looking for stuff like the iRig or AmpKit try eBay as you can get decent deals on stuff like that there. If not try one of the following retailers.

Dolphin Music Always a good place to find hardware for your mobile rig. Dolphin
Absolutemusic Another good store to find music hardware also has a good selection of stuff is worth checking out if you're in the states! Last but not least

Can't find what you want? If you think there's a category missing then why not suggest it by emailing
