Thanks for the kudos Sween.
David here is some help, even if you could source some 2.5 "cheaper", it's a BIG box, and cost a mint to ship these days UPS, the you aren't even sure you got a reasonably flexible, lightweight, quality product.
So if you can pick up local, or ship a short distance and save some money on shipping, you just might be ahead, and possibly be making a business relationship with someone local like Judson Labs that will pay back dividends for your business technical questions and chemistry advice years down the road.
Plus, you could also pick up some quality 2.5" hose adapters, connectors etc...
