Well, my absolute best offer is in, and I broke the house rules in order to make it.
Since it was below the tagged price, I have to wait for the consignment owner to give it a thumbs up or thumbs down.
Unfortunately, I won't be back in town during the shop's open hours until next Thursday night, so even if the consignment owner goes for it, he won't get his money for a week unless I can weasel a "by appointment only" meeting before then.
Anyway, gave it my best shot. Stay tuned to see if I scored it!
++++++++++
EDIT: Score!!!
As it turned out, I had missed the shop's voicemail message that the owner had accepted my offer. I changed my weekend plans and was able to pick it up yesterday.
Pix to be posted when I'm back home mid-week.
