LG today announced a limited time promotional offer for the leather backs for the G4. Under the offer, the company will be offering customers who pre-order a leather back cover now, a second leather back cover for free. The promotion lasts throughout June, so interested buyers still have a lot of time to make up their mind. LG is offering the leather panel back cover for the G4 in yellow, red, blue, orange and pink for $69.99 apiece. The second leather back panel does not need to be of the same color, and customers can chose whatever color they want and its price will automatically be reduced to $0 at the time of checkout. The LG G4 went up for pre-order in the United States last month, and the company was offering customers who pre-ordered the handset a free microSD card, a spare battery and a charging cradle. → LG G4: Buy one leather cover, get one free
