You average flea market there is many items well above $20 dollars I had a peddler try to sell me one of those cheap $10 dollhouses they sell at walmart during Christmas for $60 bucks.
I have 1 lady in florida that runs a flea market that buys from me all the time. She specializes in the Bedding and Giftware items. She does very well on these items.
I am actually planning on renting 4 booths at our local Civic Center Flea market and loading up the tables with several hundred items.
These items should sell themselves. If they have the original price tags on them leave them on. They will help especially if your selling a $120 item for $35.00
I have 2 pallets approx 600 Units of Martha Stewart Bedding I expect to sell pretty well at $20-$30 a unit. since the average price on each of those units are $80-120 People are looking for a deal. When they find out through verbal communication where the items came from they will buy in a heartbeat if you give them a good deal.
