The G4 is easily the best LG smartphone available at the moment, and if you're particularly fond of the leather back option or of manual camera controls, it may be the best choice on the market. We've seen some significant discounts on the phone before, but one eBay vendor has the best price yet: $339.95 for a new, unlocked GSM model. Depending on where you buy from, that represents a discount of $100 to 300 or more off of the retail price.
This particular model appears to be the international LTE version, and the description says that it supports LTE bands 2, 4, 5, 12, 13, 17, and 25. That should cover AT&T and T-Mobile, plus similar MVNO carriers, in the US (Sprint, Verizon, and other CDMA-based carriers are out of luck). At the time of writing, only the black leather model is available on eBay. Some don't like the stitching on the rear panel, but I think it's rather fetching.
US shoppers can get free economy shipping, and the seller will also ship to quite a few international locations for an extra charge:
Shipping to: United States, Canada, United Kingdom, Denmark, Romania, Slovakia, Bulgaria, Czech Republic, Finland, Hungary, Latvia, Lithuania, Malta, Estonia, Greece, Portugal, Cyprus, Slovenia, Japan, China, Sweden, Korea, South, Indonesia, Taiwan, South Africa, Thailand, Belgium, France, Hong Kong, Ireland, Netherlands, Poland, Spain, Italy, Germany, Austria, Russian Federation, Israel, Mexico, New Zealand, Philippines, Singapore, Switzerland, Norway, United Arab Emirates, Qatar, Kuwait, Bahrain, Croatia, Republic of, Costa Rica
As always with deeply-discounted phones on eBay, there's no telling when stock will run out. Get an order in quickly if you want one.
