I think that you are looking at it backwards...
The regular price was already determined before they left Wauseon OH, but Busse wanted to offer a few special deals for those who put out the money to come to BLADE in spite of a rough economy. If you think about it, those who didn't come and who will pay the regular price will come out waaaay ahead because they didn't have to pay for their flight or gas to BLADE, a hotel room, meals, etc. or the TAX that we paid on knife purchases at the Show.
In short, they didn't set the prices with the intention of raising them, they set the prices with the intention of lowering a few prices and offering a few deals one time only for BLADE attendees.
I think that this was very kind of them to do, and they didn't have to, those knives would have sold either way.
