After speaking to ChoicesUK on this forum, they informed me that they're going to reduce a few prices on the nintendo wii's games such as:
Rayman £24.99 after voucher (£22.49)
Redsteel £24.99 after voucher (£22.49)
Super Monkeyball £27.99 after voucher (£25.19)
Please bare in mind that the pricedrop will be later today, so the deal probably isn't showing up right now but if you're after these games, try and hold off for a little bit to get it a little cheaper.
Don't forget to use Quidco to save an additional 5% cashback.
Hope this helps :)
