Or maybe E-bay or Craigslist? That's where I'll probably have to go, when I finally have to replace the vintage Samsonite train case that I've had for four decades.There are a couple of sellers on Ebay that sell NEW Hartmann tweed mobile travelers for about 1/2 price of retail. I bought the 2nd mobile traveler from an Ebay seller. It came in the original Hartmann box just like would be delivered to a retail store. Complete with warranty and luggage tag which can be monogrammed by Hartmann.
Hartmann is right now having a sale on their Intensity line. 20% off which makes the prices much more reasonable. http://www.hartmann.com/shop/product...Garment%5EBags
$562 for the 50" mobile traveler Intensity is still expensive but with the lifetime, unlimited warranty (other than cosmetic damage and lost/stolen bags), it makes Hartmann bags truly a lifetime purchase. http://www.hartmann.com/shop/images%..._Guarantee.pdf
Those rolling garment bags are truly a one bag trip. I use regular wire hangers with dry cleaner bags to hang up just about everything except lingerie and t shirts. I can put about 8 hangers on each end of the bag with khakis, tops and a couple of fancy dresses. Still have room for a couple of pairs of shoes, underwear and misc. Bag very rarely is over 50 pounds and I never weigh until I get to the airport.
As for finding them at yard sales-small towns, yes. Large cities-probably not. Ebay and Craigslist sellers hunt them down because they can be sold used for relatively high prices on Ebay. I found a foldover Hartmann tweed garment bag at a swap meet about 7 years ago. I didn't like it because it had to be carried over your shoulder. I sold it on Ebay for $75.00. I paid $10 at the swap meet. But keep looking, particularly in higher dollar retirement areas. There is a LOT of Hartmann in Sun City, AZ and other upscale retirement communities, certain areas of Florida and Texas. Good luck!!!
