This question is not price shopping assistance. It is, at the core, a question of how to get something in the U.S. There are multiple examples of similar "where can I find" questions on the site.
Where can I find an iodine crystal water purification product?
Where can I find good topographical maps of Peru?
Where to get replacement parts for a Ugly Stik GX2
Refillable camping stoves for use in the UK
Where can I get long but light bottoms for water?
Where to buy ethanol in Canada?
Price shopping means price shopping, not anything that can be shoe-horned into the broader category of shopping.
"Sourcing hard to find gear" may be a topic the community wants to ban. If so let's start that meta and have that discussion.
I suggest before anyone does they read Robert's answer to basically that exact question: https://outdoors.meta.stackexchange.com/a/588/127 -- "Gear talk is usually the mainstay of any half-way decent outdoors site. Let's not lose sight of that. I wish there was more of it on this site." (emphasis mine)
Also consider in our general outlook for flagging - Should we be more critical of questions (and closing many more than we do) to maintain quality of site?
