ASDA were previous doing this at 2 bottles for £5, now it is further reduced, in Northern Ireland anyway to £2 a bottle. As well as this there are many other CarPlan products all priced at £2, including carpet and upholstery cleaning, leather cleaning, back to black, bumper shine and car shine.
Most of these products sit around the £4 - £5 mark, but the demon shine caught my eye as it was £7 in Tesco the previous day.http://www.google.co.uk/products/catalog?q=demon+shine&hl=en&client=safari&rls=en&prmd=ivnsfd&bav=on.2,or.r_gc.r_pw.&biw=1440&bih=838&um=1&ie=UTF-8&tbm=shop&cid=16197269745502523961&sa=X&ei=909OTpfmKc-88gOKgP3TBw&ved=0CFIQ8wIwAA#ps-sellers
I know demon shine will never replace a good wax, it is good for a quick cheat and for £10 you could effectively buy enough to do your motor once a week for a year! And to be fair it doesn't do a bad job if you dry it off, here's a quick glimpse of what it did to my motor yesterday!http://i278.photobucket.com/albums/kk84/TomBoyNI/P1020099.jpg
Anyway I think it is well worth a go at this price :)
