Aristo posts a once every 4 year sale and of course the website crashes and the phone network is down! Go figure…
lol, they dont actually want you to buy anything, duh!!!
Online store seems to be working for me.
The Aristo web site/on-line store has rarely crashed in the years I have looked at it and that is daily. In fact I only recall one occasion sue to hackers.
So, we must assume that they are getting lots of business.
Shame we overseas cannot join in. I could have easily been temped with some 2-bay hoppers, tanks cars etc.
At least the recompense is that I don’t have to smoothe the path before announcing that more trains are on their way. 
The on-line store worked just fine for me. I bought 4 coal hoppers, two Northern Pacific and two Great Northern. This is the first real purchase I’ve made in a couple years just for me. LOL
