[HeyLaughingBoy]

There's a vendor I deal with that does something like this. They have an online catalog and prices are listed, but to buy something, I have to email them and then they respond with a link to their fulfillment partner.

At first I thought it was really dumb, because they're in a technology sector and deal with engineers all the time. Why not just take me to a shopping cart? But then I got an email that said something like "HeyLaughingBoy, I noticed you bought 5 units of $SENSOR in July and another 10 units in August. Would you like to discuss volume prices going forward? We can scale the price to your estimated annual volume..."

I thought it was a great idea to get a dialog going with someone who looks small time (me) but could become a major customer. This way, they build a relationship with me before I just start looking for someone cheaper as my sales grow. If they just listed prices at preset volume levels, that would never happen.
