We're all aware of the issues around 'pricing' in TO and how there is no up to date list of 'prices'. Most people rely on asking for PC (Price Check) in the TO, However this does lead to multiple repetitive requests during the day, in particular for adventure ls, which don't really change much (except during events).
How about a sticky giving the prices for (off the top of my head):
BK ls
RB ls
VLT ls
CLT ls
SLT ls
BLT ls
2T ls
Oil Lamp ls
