After some moaning on live chat they agreed to perform a manual £20 refund on the item after delivery was completed. It seems they have changed the T+C's to prevent you using it on PV or Video Game items but havent updated their customer facing T+C's so theres still a loophole there if you can be bothered.
That wasn't a requirement before - code worked fine when the deal was posted and for all previous promotions!
Just tried to order the SNES Mini and it wouldnt apply. Was told this on chat: I regret to inform you that. Baby formula, products from local shops and markets and PC/video games are excluded from the promotion. The promotion is limited to one redemption per customer.
Cool, no problem. :-)
I've just updated this thread with new prices, offer ends on the 30th August! If you guys spot any more then let me know and I'll update the OP!
