Where is that website which advertises where the travelling bike parts sales are?

I have been to a couple, but no longer receive the fliers.

Usually in schools on Sunday mornings, selling things like Shimano parts good and cheap - big artic lorry parked outside with stock in it.

Ring a bell with anyone - I remember going to Stockport and Wythenshawe, but think they travel across whole UK.
