Amazon isn’t the only game in town when it comes to deep discounts on popular smartphones, and while Amazon’s 4G phone sale is certainly impressive, LetsTalk has a few even more appealing deals for Memorial Day. From now through May 31st, the online retailer is offering several incentives that add up to big savings on Verizon Wireless’ Android smartphones. First, LetsTalk is offering free overnight shipping on all Android phones. Add to that a 20%-off coupon for all Verizon Android phones (coupon code 7c7f3319) and we’re looking at some of the lowest prices we’ve seen yet on several sleek smartphones. Some highlights from LetsTalk’s sale include the Motorola DROID X2 for $120, the Sony Ericson Xperia PLAY for $80 and the HTC DROID Incredible 2 for just $64. Countless other smartphones are already priced at $0.01 or even free, so Amazon clearly has some competition over the coming long weekend.
