I have about 20 Domaine 12-bottle flat (2x6 bottle) storage boxes available, like these:
Amazon.com: Wine Storage Boxes - Layflat Style - 12 Bottle 750 ML (QTY: 10 Boxes): Home & Kitchen
They were used once for a wine move last year.
I’m in Ft Collins, CO and could travel a reasonable distance to hand these off.
