Zagg.com, the US based company which sells the famous "invisible shield" is having a sale this Monday! Everything on their site will be discounted by an extra 50% off the marked prices.
As far as I know, you don't need a coupon code or anything, the discount should be automatic at the checkout.
If you don't know what they do - invisible shields are handy protective shields for your electronic devices, such as your ipods or your PSPs. It's basically a tough sticky plastic, shaped to fit your device exactly. My OH uses them on his HTC touch cellphone and his Creative Zen mp3 player.
I rarely post about non-Canadian companies, but Zagg is one US company which I don't mind posting about. They have an excellent product, excellent service, and ship worldwide at very reasonable rates (I did a test order and the shipping was only a few bucks).
Zagg are really excellent though, we've used them a few times in my house. There's one drawback though:
The touchscreen is no less responsive, but you do get a slight, (and I mean slight), rubbery feel to the touchscreen due to the material used in the Zagg-shield [Mobot].
