I live in Ft. Collins and had the same issue. It's an easy fix. I went to my King Soopers (Kroger) and had them order it for me. They called me when it got in and I paid the regular price without shipping. Took about a week. By the way, I tried making buckboard bacon, but failed first time around. I travel too much and it didn't get properly cured, but will try again.
Also, I grew up eating cured Hog Jowl which is really nice. King Soopers orders it in for me, about a case a year, and again no shipping charges, just a phone call telling me its in.
If you have a large national chaing supermarket in your area like Kroger you can have them order about anything you want. I wanted some sodium carbonate (not sodium bicarbonate) for making detergent a few years ago. No problem. Now it is stocked and has become a fairly common shelf item.
