Most reputable breeders are not going to change to much in price a week prior to a show? Not sure, I would go to the show and see the animal in person anytime I could, again with reputable breeders and people here on bpnet I would trust their judgement as well.

Brian at BHB
Justin K.
Adam at 8ball etc etc etc are just a few that i would say just pick one out and send....Wait for the show is what I would do, never know what you will find
