Do you want to buy Google Nexus 5 but the device is now sold out in Google Play Store? There are some Web sites you can check out to purchase the new Nexus smartphone.

Just after two days, the newly released Google Nexus 5 is already sold out in many markets worldwide. The much-anticipated device went on sale last Friday, but both black and white models in 16 and 32 GB variants are now listed as out of stock.

Google has yet to announce when it will replenish stocks of the handset. The 16 GB Nexus 5 sells for $399 while the 32 GB variant costs for $449.

So far, Australian carriers revealed no plans of offering the Google-LG Nexus 5. However, LG will release further details regarding additional sales channels in the country once the new device has completed "local network testing," the company informed the public via a media statement last week.

The fast selling out of Google-LG Nexus 5 seemed like a déjà vu of last year's LG Nexus 4 stock debacle. The latter was out of stock in the Google Play Store most of the time.

Here are some of the Web sites that you can check out if you are itching to get your hands on the Google-LG Nexus 5 and cannot wait for Google to bring out more stocks.

The Google Nexus 5 is being offered in eBay. A seller is listing the 16 GB variant of the smartphone for $380, which is slightly more expensive compared to the listed price in Google Play Store. The 32 GB variant costs more than $450 up to over $500.

The new Nexus smartphone is also available in MobiCity for a much expensive price. The 16 GB model is offered for $550 on its Web site.

In the U.S., consumers can buy a Sprint Google-LG Nexus 5 in Best Buy for only $150 with Nov. 8 as its ETA, reports Android Central. So far, other carriers have not revealed their plans in offering the device.

In the UK, Carphone Warehouse and O2 both offer the new handset from Google. Carphone Warehouse offers the 16 GB version of the phone either on contract or SIM-free. However, only the white version is in stock as of this writing, so consumers who want the black version may have to wait for new stock. Meanwhile, there is no stock problems reported in O2.
