I followed your link and decided to check out the rest of what they had. It looks like they may have an on-going sale on 16 oz. 5 yard PV casuals for around $43. I made a bid on a 24 hr. auction that had 18 different tartans listed as options; after it closed, I found the same sale started all over again.

Here's the current sale, and if it's closed already, you'll probably find it open somewhere on this page.
