Bargain Homebase loft insulation

Yesterday I had a stroll through Homebase Clearance for the first time in a long while. I happen to come across a large stack of loft insulation. Our house is very cold in the winter and loft insulation is something we've looked into before. I did the measurements and calculated that I would need 22 rolls which they had. They were priced on the shelf as £11 including discount. I got to the till discover that the ticket was wrong. They should have been £8.39. that's a first for me. I checked with wickes online price and I reckon I have saved myself over £100. The down side is that I've had to make 4 car journeys to get it all home.
