I've just got some from www.soeasyblinds.co.uk after going all round the houses trying to find ones with controls on the correct side. I'm really pleased with them (wooden venetians). Managed to find a 10% off code somewhere and got 5% cashback from Topcashback too.
Not prepared to pay the price quoted by my local blind shop when I could get the same roller blind online for half the price. Yes, they would install, but I can't imagine it would be too difficult to DIY. My only concern is whether the quality will be as good (fittings etc.). Has anyone had any experience of ordering blinds online and could you recommend a company?
