So, the going rate is now $8.15? We have a joke at my buddy's bicycle shop. "Everything we don't have is on sale."
My experience does not match your buddy's. My local dealer's stocks ebb and flow, but there usually isn't much of a regular cycle to it. The prices and stock seem to be based on what's available within a decent distance, or if they have large custom jobs going on.
For instance, one of the dealers is a large archectual woodworking shop. If he's doing a large project in a wood that doesn't normally fly off his racks, he'll buy extra, at the lower price, so he can offer a better retail price. This, in turn, encourages the smaller guy to stock up. These guys tell me that a big part of their cost is getting the truck to the door.
Some of my other local sources are not actually dealers, but cabinet shops willing to sell small amounts to those who ask. Same thing there, if he dosen't need it, the price goes down to make room for the material he needs.
BTW, some small shops, where you're dealing directly with the owner, LOVE cash. I've bought wood and metal from small local factories and gotten GREAT prices for cash. The green presidential stuff, not a check.
