In a past life I managed a service dept that delivered services around the globe (new york, london, singapore, ...). I had staff working for/with me in those locations and in order to deliver the service we bought high end ICT gear.
I had the choice where I bought it, either we could buy it centrally and ship it, get it through customs etc, or we could buy it locally and be done with it. Now for certain equipment we had deals in place with the manufacturer and for other stuff, we usually used a local supplier for speed and flexibility.
I've had a number of suppliers over the years removed from the supplier list due to them blocking me based on geolocation. Sure I could easily tunnel though our local internet connection, but it's a pain to have to do so.
If I can't see their stock levels, their pricing, etc and compare it to my other options - well then they will not make a sale.
I've ran into a supplier near Washington DC at a point that had a huge warehouse full to the brink of equipment but they for some silly reason assumed that not telling me their stock depending on where I was would be beneficial to their business. I did check it: if you had an apparent US geolocation they did show their stock levels, with an EU based one they did not show it. In the end they lost a lot of business just by refusing to show me their stock levels. They delivered fast, had a huge stock, where competitive on price, had good terms etc. But the extra trouble to be able to see their stock levels meant I usually went elsewhere. For one reason: it was simpler if I wasn't on a desk in the US.. .
