I went to the Derby branch recently to buy some Miniline guttering for a shed. However Wickes have now changed the products to MiniFlo and BEWARE the two are not compatible. Having bought all the bits I needed I started the job some days later. It was then that I discovered that all the parts were MiniFlo except for the guttering end stop, which was the old Miniline. I returned to Wickes (a 30 mile round trip from were I was doing the job) and found that they had both Miniline and Miniflo products mixed on the shelves. I pointed this out to the cashier who said that they keep the older stuff in case anyone still wants it. I pointed out that it was not obvious which is which and could easily be confused. They did not seem at all concerned and even charged me 29p extra for the replacement end stop!
