Many of the retailer's prices are already marked down (except for the Seidio, everything is less than $10), but using the 30htcoff code at checkout will save you an additional 30%, which brings some items down to under $3!
The code is only good "for a limited time" and I can't personally vouch for the company's service or product quality, but the extra discount makes the already attractive prices pretty hard to resist.
