I looked many years ago (estimate 15 or so) and there was either none or one. Actually one = none.
The retailer never had any in and if I recall as there was an "offical" seller then Stellarvue wouldn't sell direct.
So a retailer who had none (ever) and unable to buy direct because there was a retailer. Think I replied to SV saying they needed to look into the situation. And then I gave up.
Now that you mention that - I do remember at one point a London astro retailer did describe themselves as an SV dealer at least on their website - but never had any SV products in stock..,
Nothing against, them - I actually bought quite a bit of stuff there, just not SV
Its really not a problem buying direct from SV - at least from the UK in my experience.,
