Here on the east coast U.S., it's officially Memorial Day. To celebrate, the well-known company ZAGG (who created the invisibleShield that we've all heard of or seen in stores) is offering a 50% off site-wide sale. Everything except the Logitech keyboard case, ZAGGmate, ZAGGsafe, and gift cards are 50% off.

ZAGG is also offering free cleaning supplies for mobile devices if you tweet out or share on Facebook that a 50% site-wide sale is going on until tomorrow, May 31st.
