A couple follow up comments:
1= I rarely buy a print that goes on the wall quickly, so I'm really never looking to buy a print framed. The only times I've ever considered buying an already pre-framed print is if I have been chasing a ghost (i.e., none available for sale for a long time). I have occasionally purchased a framed print on the condition that it is taken out of the frame and is in mint condition, and is then shipped to me in a tube. But I understand that most sellers of framed prints don't agree to those types of conditions. For me, the price I have agreed to in such purchases is no more than the price I would have paid if the print had not been framed. Maybe it's a matter of semantics, but I view this as not paying for the frame up. And the seller has probably only done this for me because the print has been for sale for a while with little or no interest generated.
2= I know I've never talked to a seller about buying a print framed by Further. That would likely be a completely different situation for me than in #1 above. That is, every frame up I've ever seen Further display is awesome. I have a few myself and love them all. That said, I would have to be seriously considering hanging the poster right away to even buy a Further framed poster (see # 1 above). The point here, however, is that I would view the framing as a legitimate component of the value of the item I'm purchasing, if it was framed in a way I felt great about looking at on my wall for many years, which I am confident would be the case with a Further frame up.
3= I hear you, Corey, about your framing resurrecting various horrid condition posters, and adding far more value than just the framing cost. I don't need to see any examples to believe you. And I know you're not the only awesome poster framer in the world, so I'm sure this is also true for many other top notch framers... even if my personal bias is that you're the best... which does happen to be my opinion on the matter.
4= In summary, despite all the caveats and exceptions, my overall feeling is that the cost of framing (generally speaking) is a sunk cost that a seller should not expect to recover. I know I wouldn't sell a framed print with that expectation, so that's probably why it bugs me when a seller goes on an on about the details of their frame up. Museum glass, wood filet, custom painted mats, hand scalloped frame, yadda yadda yadda. They're selling the freakin' frame up. I want to buy the print. Thus, it's a pet peeve. I'm not attacking any framer, especially a pro like Corey. I'm just looking to add art to my collection; not a frame made from a tree from an enchanted forest.
I always defer to someone who's wearing a beater, regardless of what else he's wearing.
