Don't know about the inside market but when i used to stand the outside one with another bloke called hue we sold computers and peripherals and software.
Monday market closed
Tuesday quiet
Wednesday closed
Thursday (flea market was busy)
friday very busy (pay day)
Saturday very busy
Sunday was dead did not sell much at all.
just while on about the inside market (just to bring it back on thread) a little story
one of the stalls that used to sell eggs had trays of them on the front counter the butcher that was on the next stall nicked a tray of eggs the stall holder was telling him that someone had nicked a full try of eggs but did not know how, the next day the tray of eggs was replaced all the eggs in that tray had been hard boiled the customers that came back complaining, he did see the funny side and we found it hilarious

If by any chance you where one of the customers that bought them i hope you found it funny too
and yes the bucher did pay for the eggs
