I went into get one at the weekend although it wasnt the one in Forest Hill. We went out for the day and some how ended up getting lost around Deptford or somewhere, where we pulled up to enquire about the Christmas trees displayed outside.

It was quite clear that they just named any old price according to what they thought you would be prepared to pay. In short, if you're wearing smart clothes and remembered to shave on that day you're told ?40 or ?50 otherwise you may get it for cheaper. As we walked out the price magically came down to ?30.

I expect its the same everywhere.
