Harbury local market is organised by a small group of helpers with support from the parish council. The stall holders fee, raffle collection and money from the sales of teas goes directly to a nominated local charity each month. This market usually takes place on the last Saturday of each month.
Southam market is run by Southam First, Southam Lions and WI. Southam market supports a different charity or local business each month.

Both markets have a selection of produce stalls including fresh meat, honey, eggs, cakes, chocolate, alcohol and dog treats.  Artisan crafters also have art, cards, candles, aprons, cushions, cuddly toys, bags, jewellery, soaps and gifts for sale.
