Wickes submersible water butt pump. Reduced on on the website at £19.99, but reduced further to £10 in store, less the 15% offer.
There are 10 left in Coventry, and there seems to be 2/3 in many other stores nationwide. Lady said they are reduced to £10 across the country.
I was quite happy with the £19.99, so really pleased. Hope this helps someone!
