Went in-store today (Bury Branch), there was a large shelf with at least 20x sets reduced from £29.99 to £9.99. It's a set of their platinum series products so they really do work well, especially the car wax. I also used a 15% off voucher from their current Christmas promotion outing the price down a further £1.50 making the set a mere £8.50. The set comes in a transparent zip bag which contains:
Platinum Car Wash - 500ml bottle with a rich lather formula
Platinum Car Wax - 500ml bottle with Brazilian Carnauba & Bavarian Montan Wax to protect & shine!
Platinum Wheel Cleaner - 500ml bottle is suitable for alloys, chrome & steel wheels
Platinum Cockpit Shine - 500ml bottle adds a deep lustre to all interior trim
2 regular sponges
P.s. I think that the deal is nationwide as it has appeared to be on their website before.
