Handbook for groups running a flea market

Flea markets have two seasons, and they are not the same size. Of 119 market weekends we have read, 75 fall in autumn and 42 in spring. September is the busiest month.

Summer is empty. We have read 0 market weekends in July. That is worth knowing for a committee considering an off-season date to avoid the competition: people are not looking for flea markets then, and an empty Saturday in July costs the same volunteer hours as a full one in September.

In the autumn season the market competes with many others. In spring it competes with fewer — but the season is shorter.

Of the 17 markets we have confirmed against the organiser's own page, 17 are open on Sunday and 13 on Saturday.

Sunday is the day nobody drops. If the market runs for only one day, that is the one most groups choose — and a market closing on Saturday afternoon misses the day people actually have time.

Multi-day markets often start on Friday evening. The Friday is usually not selling but donation drop-off — worth stating clearly, because a customer who turns up on Friday to a closed door does not come back on Sunday.

22 of 61 groups write about when they accept donations. That is the window nobody else covers, and it decides what you have to sell.

The recurring pattern on the pages we have read: one fixed evening a week in the run-up — often Tuesday between 6 and 8 pm — and then an extended period right before the market, often the whole preceding week. Several also run a drive-in evening the day before, where people do not have to carry anything themselves.

What is least clearly stated on most pages is what the group will NOT accept. Large appliances, mattresses, monitors and broken furniture turn up regardless, and every load you have to haul away afterwards eats into the profit. Put it on the page before the market, not after.

The categories the groups themselves list on their pages, in the order they are mentioned most often across 132 pages. This is not the same as what sells best — it is what the groups consider worth mentioning, and therefore what a customer expects to find.

Vipps is mentioned on more pages than cash. Accept both anyway: flea markets draw people who do not use apps, and a queue that stalls because the network is slow in a school gym is a real cost.

A café appears on roughly every fourth page. It is rarely mentioned as income, but it is the reason people stay longer than they meant to.

A Sunday auction appears on several pages. It moves the large items — furniture and whatever would otherwise be left standing — and gives people a reason to come back on the second day.

Write the address as an address, not just «at the school». We have had to look up school addresses in the company register to place markets on the map, because the page only said which school it was. Someone about to drive forty minutes needs a street name.

We have built a page for each of 2631 groups in the Norwegian public registers. Yours is already there, with its name, founding year and organisation number — and it is yours to take over.

Once you take over the page, you can add the market yourself. The date then appears on the municipality page, on the map, in search and in the calendar file people download. You get a link that lets you correct the date without contacting us, and that link keeps working when the committee changes.

The organisation number is worth showing wherever you write about the group. It is what people need in order to give you their Grasrotandel share.

Accounting duties, VAT compensation, criminal record checks for volunteers, insurance and alcohol licences are real questions a committee has — and every one of them is something we would be guessing at. Wrong advice is worse than none, so here are the bodies that actually administer them.
