If you have ever used an otterbox case before, you know how good it is. Now it's finally available for the iphone 4!
There is a coupon for 10% + FS with no Min but I cannot list the coupon here because the url has been blocked. Go here and it's the first one on the page.
Note: If you are not in a hurry, you can pre-order it from MobileCityOnline for $35 w/ free shipping with expected arrival in late August.
