The Google Play gift cards redemption page has gone live in the UK since late last month, but there doesn’t seem to be any solid information on where and when folks can purchase the vouchers. There’s one place on the Web, however, where you can get them for free.

Retailer Phones4U is in the mood of giving, as it offers a free £20 Google Play gift card when you buy the Galaxy S3, the Galaxy S3 Mini, or the Galaxy Note 2 from its online store. Note that the offer is only valid if you get the phone on contract.

You can claim the voucher by going to the following website, where you have you to enter your name, phone number, e-mail address, and the phone’s IMEI number. You’ll then receive the Voucher code, which you have to redeem on Google Play no later than the end of March 2013. The credit is good for apps, music, books, movies, and magazines.

The promotion tells us that Google is likely to officially launch the Play Store gift cards in the coming days. We'll keep you posted.
