I spent all week researching digital cameras with my colleague who has the liberry credit card. We drove all around town and went to several computer stores with no customer service. We finally located a store that had 14 in stock.
We talked to the guy and told him that we can spend a max of $2500 a day. He initially calculated that we could get 7 cameras for that price. Then, magically, he figured we could get 8 of them when we told him we'd need to order about 30 more. He was so happy- here's my business card, let me know if I can help you!
Probably on commission.
