Not really a deal, not really a discussion, more of a PSA about my new BFF. One4All. Discovered that Perks@work give 9% cashback on it. That's on top of any cashback you can get from the retailer (via TCB or QC), extra discounts from coupon codes and cashback from the credit card you'd use to purchase the O4A card.
Now O4A can be used online at Argos, B&Q, H&M, GAP and a few others.
