I agree with retail therapist. Get your pieces and money due back IMMEDIATELY. No 'ifs' and 'buts'. Take a friend/witness with you and do this at her market stall- a large, imposing friend, preferably male:) Refuse to leave/stand in front of their stall/sales items until you have all your pieces/money due back.

Giving any seller your items  'On Consignment' for an unspecified period of time and without any written paperwork is asking for trouble.

A simple itemised & dated receipt written by yourself at the time.Include a 'damage to stock' clause and a 'stop' date e.g. for 6 weeks time from receipt date-along with a designated/agreed upon 'meet point' for a handover(write this in), write the sellers full name, address and contact details,hand to the potential seller to sign also, make sure in TRIPLICATE-give seller a copy, you keep 2 copies.

To keep the seller on their toes you should make the effort to go to a couple of their market days and make an appearance. The aim is to build a business relationship but also lets the seller know that you are serious about keeping tabs on your stock!

If this first 6 week period works for both seller and yourself repeat the process with a further receipt and follow-ups.

On Consignment can work but you have to set the parameters, afterall, the seller is getting FREE stock.
