Just been in to my local Wickes and there seems to be a massive deal for 3 for 2 on all paints including Dulux! Asked at the till too and it's 33% off the total bill rather than the usual cheapest item free. Some big discounts on accessories as well.
There's some real bargains on tiles and flooring too with upto 50% off some lines in what seems to be clearance deals.
I thought I'd ask whether I could use my trade card for an extra 10% too and it turns out you can which makes this deal crazy. So if you're in the trade make sure you ask at the till to sign up to get your 10% off discount code it only takes 1 minute to sign up.
