Roller Skates For Sale, East London Can Anyone Give Me Any Advise On Selling Things At A Car Boot Sale?

Can anyone give me any advise on selling things at a Car Boot sale? - roller skates for sale, east london

Could go to sell a sale of the boot and things, but I'm not sure how they sell. I also have the prices on or leave them wondering how they are, and then haggle a price or something. I sell some Avon bubble bath 500ml, 250ml bottles of shampoo and conditioner, the Avon silver watches, brushes, brush set, makeup brush, and small number of skin products. Avon products are a couple of years, but I think it's been hermetically sealed bubble bath and it smells good and looks good, you can smell the shampoo and look good, but not locked and there is some skin, make-up a few years and whether these or leave it to sell. Things are basket weave using irons, but in good condition, 3 clothing, r the numberOller pads, bath soaps, bath blow up the pillow, red card and envolope, watercolor paper A4. I am also authorized to sell part of the salad which was planted in my garden and some red plums? How should I price these things?
