Instructions:Easy use the code and voila. Code was sourced from a google advertisement and is thus public. Expires 5pm 25 November apparently.
Restrictions I noticed today when trying to use the code:
1. Cannot use this code to collect instore - online only.
2. This code will not work if you use quidco, topcashback or any referral link to get to the currys website, it will say it is expired but isn't! Clear your cookies, go to currys again, and voila it works!
