Despite an image of the Sony Xperia Z2 appearing a few months ago, it doesn’t look like the device will actually be launching in the US soon. So you need to either import the device or buy it from a reseller. Those can be costly options, but now a deal has surfaced on eBay.
Currently the Xperia Z2 deal on eBay will cost you only $672.98 and you can get it with free expedited shipping. This is a lot less than through other resellers, some of which sell the device for north of $700.
This deal might be better than what Sony themselves will charge later this summer. The listing appears to indicate that the Z2 they are selling will work with AT&T’s LTE network. So if you want an Xperia Z2, you should buy this while it lasts.
