Due to arthritis, I need to buy a wheelie bag for my euphonium. Allora seems to be the only company that make wheelie bags. Every site and store on line I've tried (Amazon, eBay, Woodwind and Brass) etc. has none in stock and back orders are delayed 5 months or more. Does anyone know of a store that has them (or another wheelie brand) in stock that I can contact directly? I would need their address and phone number since I live outside the US. Thanks!
