I watched the show that they had on TLC. It looks pretty intense!!
I'd say you should definately have a laid-back attitude to be successful. Some of the ladies were kinda spazzy & it was annoying to watch them so I can imagine how irritating they were to everyone around them!!
Most people wore matching outfits or something to group them (ie hats or something) so they could ID each other in a crowd. Lots of yelling, lots of grabbing, but lots of deals! lol
That's all the info I can give you, from watching the show
