How about "In Stock" or "despatched" - the John Lewis way
Gets you to buy rather than find another supplier but Johnlewis.com have a new meaning - not on John Lewis premises. Indeed in my case not even on the supplier's premises or even capable of being manufactured as discontinued. Then there's "desptached". JL think that this means that is between 2 warehouses and not on its way to the customer but nobody really knows where it is so meaningless. It seems they have 2 ways of selling you a high price item (over £1,000 in my case) - if they have it in a nearby shiop you can have it in a couple of days, if not then somebody in Germany may or may not be making it and you can have it in a couple of weeks possibly. An interesting internet shopping experience!
