There's a good chance that you are paying too much for your iPod Touch 4 accessories. Stay away from overpriced retailers such as the official Apple Store, as they are known to add great premiums to the prices of their accessories. Online retailers that have a marketplace for wholesalers is where you should look for these accessories. Try sites like Amazon and eBay so you can find the same accessories at really low wholesale prices.
