I think the ipad is a fine tool to spot check, but you have to match the speed and rhythm of the buyer. You can tell them to separate cards you want to look up, and while you research, you can keep confirming / denying other offers.

That said, shame on you for not having your stock in Trader Tools so you can just open up the list and check as you go.

I definitely agree with not telling them what you’re looking for immediately. I will say that I’ve sold to quite a few dealers at GPs and I do “Ogre” my stuff ahead of time and usually the good dealers are happy to work with you, sure sometimes they will still try to get something lower, but they rarely push you on anything. However, the one issue I can see with using your phone to check the prices…is that it can add a LOT of time to the transaction and you have to remember the buyers “time” is VERY valuable at a major event. If it takes them 5 seconds to look up a price on a card and you 5 seconds to look up one..that’s 10 seconds per card…or 6 cards per minute…if you’re selling 300 different cards…you’re taking up 50 minutes…and that’s at one dealer..if you’re planning on taking the same stuff to different dealers to get the best offer…you’ll use up a LOT of dealers time.

I have also found that Ogreing Boxes works quite well when selling to vendors at events. By having the cards pre-organized by buy price ($0.05, 0.10, 0.25, 0.50, etc.), the vendor can look through the organized pricing sections and quickly say whether or not they will buy the card at the specified price. One vendor actually thanked me for providing cards in such an organized fashion, as it made the process faster/smoother for them. This can in turn lead to more favorable offers from them ; )
