The only way to tell one cell phone from another is through customization, whether it’s covering it with a colorful case or squirting it with dish soap so it foams each time it’s touched by a sweaty hand. Help your phone stand out without the mess with today's Groupon: for $20, you get a $50 eGift card to iSkin, a manufacturer of protective products and audio accessories for personal digital devices.

iSkin holsters an array of products to shield fragile techwares from bumps and bruises, deck them out with fashion-forward styles, and maximize their potential with slick accessories. Complement manicured fingers with juicy colored cases, such as the solo FX ($34.99) for iPhone 4, which comes in five translucent hues, or slip MacBooks into chic Soho slips ($49.99/$54.99) and iPad 2's into iSkin smart covers ($49.99). Sets of earTones ($39.99) lend a current of booming bass to let listeners bob heads to powerful string-theory lectures. Shelter keyboards from dust, liquids, or jelly-donut residue with ProTouch coverings, styled in single ($24.99) or multi-colored ($34.99) for vibrant workspace inflections. Alternatively, the cushy Lil Keeper ($49.99) hugs handhelds in an embrace of Italian nylon and includes a lanyard in case the device wants to break off to sniff an attractive Walkman. This eGift card may also be used toward shipping costs affiliated with any item in the iSkin store.
