We also got ours at the Samsonite outlet. It was a few years ago, but they were $50 then. Back before airlines added luggage fees, I've even put it into a suitcase to install it on a rental van at our destination.
I just commented when we used it a couple of weeks ago how many times over we've gotten our $50 worth out of it. We typically take it with us in a box and then use it to pack any purchases we make on the trip. Or to pack the dirty clothes and the valuables go inside the van.
Not long after we bought it, DH pulled too hard on the strap and broke a buckle. We went to Samsonite to try to buy one and they insisted on giving us a whole new bag.
