Payment at card shows?

[Donscards]

I was at that Chantilly show and it could have been me the collector is talking about---Yes cash is King--also I take paypal and checks if I know the person or he has good references. I don't take credit cards---and like another person said, you have to be carful on chargebacks---I also have a flip phone---sorry I love it---I do lose sales at shows because I don't take credit cards, but also usually it is a high demand card and will sell at another show.--Many dealers I know over the years only take cash for many reasons and when I go to major shows , I take cash to buy--it works better for the collector who is selling his cards.
