Three/Four years ago I was paying roughly 12p a jar with lids from C.Wynne Jones..just got another batch delivered today and it is working out at 48p per jar and lids.. is is just C.Wynne or is everywhere else shooting the Prices up..
If you want to buy around 2k of 1b jars bulk buy you can get them for around 19p inc lids:

Maybe organise a pallet with some other beekeepers and the price would be reduced or if you produce loads yourself, press that order button!!
