Convention advice

[buymycards]

Have everything organized before you leave home. Signs made, every card priced, everything boxed up and organized so you can set up quickly. Get to the show as early as possible and get set up as quickly as possible. There is a good chance that most of your big sales will be to other dealers before the show opens to the public. Have a PayPal credit card app for your smartphone. Make sure you have plenty of change so you can break $100 bills and $20 bills. Keep your cash on your person so no one can steal it. Make sure you bring extra price stickers, a marker, a pen, a notebook to record sales and purchases, a copy of your sales tax permit, price guides, extra top loads and penny sleeves, small shopping bags and small boxes to bag up purchases for your customers.
It doesn't hurt to have a large bowl full of candy at your table with a "free" sign posted. Bring an appliance dolly to haul your stuff in and out.

Be prepared for offers on your merchandise. Nobody will pay the price that is marked on the card. Decide before the show how much you can discount your listed prices.

Most importantly - With every customer that comes to your table, greet them, smile, look them in the eye, ask them if they are looking for anything special.

Look at their clothing. Are they wearing a Yankees hat? You might be able to suggest some Yankees cards. Do they have a young kid at the show? Ask the kid who his favorite player is and give the kid a couple of free base cards of that player. Don't eat while customers are at your table. Bring some gum or breath mints so your breath doesn't smell like coffee. Shave. Get a hair cut a couple of days before the show. Wear decent clothes. Look professional. Business cards wouldn't hurt.

Good luck!
