Hi, I sometimes sell "on the boot" as we call it with my sister. It's punishing if you do it every Sunday. Up at 5, pick up sis, load up and in the queue for 6.30. Gates open at 7.30. Punters in by 8.30. Over for 12 - 12.30. Unload and home by 2.00. Exhausting. There are weeks we only take £30 (minus £7.00 entrance + £2 petrol) not great! Our best week we took about £140. we sell batteries, good seller, perfume is a fab seller, 2nd hand baby clothes on a good day shifts too... So yeah, I reckon if you have the stamina and some good stuff, it's a good little filler!
