Roadside stalls.

Wehave lots of stalls round here, there is a veggie one just a few doors up the road.
We live down a quiet lane so not much passing trade for me to sell my surplus and eggs though.
It's nice to browse and buy what people have put their time and effort into.
The one up the road has cctv now and a sign naming and shaming the cars that don't pay up with their number plate plastered all over a blackboard!

I do one every 6 weeks or so. I put a little table out in front of the house with jams and chutneys and the neighbours just put the money in the Honesty Box. If I've not done it for a while they knock on the door and ask for Lemon Curd, Jam, Sticky Toffee Pud, etc. Sometimes they leave jars on my doorstep.

I suppose you could leave a pile of little envelopes (like the school dinner money ones we had when I was a lass) for people to put their money through the door in, if you aren't keen on leaving an honesty box on the table.

Not so much in this country, but you see a lot of seasonal fruit stalls in Spain and Portugal, but when we are in Spain we usually buy fruit from the petrol stations. 5kilos of satsuma-like orange things for €3.50, a couple of kilos of cherries for €5, local grown and available in season.
They sell almonds, walnuts, onions, potatoes etc the same way (usually only one or 2 things at any time).
Olives, oil, hams, chorizo, honey and (of course) wine come from the local bodega/cellar.
