PLEASE NOTE: I've put in a link to the replacement item. This isn't the EXACT one that's Instore.
I was in Tesco yesterday wandering about when I noticed these on an end stack instore, Tesco in Leighton Buzzard.
The sign said that they were originally £86.99 then reduced to £79.97 and now £19.56
I thought £86.99 was probably a bit rich, but at £20, well worth a punt!
