This promo was previously only on Tesco Direct but is now showing in Tesco Groceries for a limited time (need delivery or collection by Monday 29th).
It doesn't include all the same titles but the added benefit is that there are a few codes that you can use on Tesco Grocery for extra savings which combined with the promo can give 50% off. Stock may vary by region.
Xbox One example: Forza Horizon 2, Sunset Overdrive + Halo The Master Chief Collection = £45 using new account code XX3FP6 or XXRHFL (£15 off £60)
PS4 Example: Evil Within + Pro Evolution Soccer 2015 + Tomb Raider Definitive edition = £45 using new account code XX3FP6 or XXRHFL (£15 off £60)
p.s. If your not too keen on using new account codes then Tesco recently sent out a savings booklet with targeted codes e.g I have a £9 off £60 code to use by Sunday
Edit: Possible £5 Quidco as well
