The way I have always read the HRO stock status is -- if a site has a check mark with a solid background, that means the physical store has that product in stock so you could walk in and buy it and take it home with you. If the site has a check mark, but not a solid background (i.e. a clear background), that meant the store didn't have it in stock at that store but you could walk in and buy the product but it would either ship from a nearby store to you or HRO would have the other nearby store get it to that store so you could pick it up the next day or so. No check mark meant that store didn't have the product and probably couldn't get it moved from another store to that store for you to pick it up.
When I checked this morning, there were 4 sites with check marks with solid backgrounds and 5 or 6 with check marks but clear backgrounds. That meant there were at least 4 ICOM R30 receivers available thru HRO but maybe no more than 4. It could be all 4 sold this morning.
