We sold at 2 markets that had another honey seller, but these markets were 200+ stalls and so were big enough to handle 2.
We did have a good run when our opposition had a break for 3 months.
Try to make your self different, one market the opp. didn't sell 500g, only 1kg, so we sold 500g jars and squeezies, he didn't sell creamed or whipped honey but we did. our 3kg buckets were $3 cheaper than his. In short we survived and did very well.
At the other market the opposition was 10% cheaper than us but only sold one variety, we stuck to our prices but would take 4 - 5 varieties plus creamed and also whipped honey.. We would also sell comb honey. We took top quality wax in 100g, 500g,and 1kg. while he sold a dirty grey brown bar about 150g.
Quality and variety is a winner at markets.
