Ask the store to check on the system if any other branches have stock.
Not going to support them.
Look at the gorgeous advice Postman gave me and in silly hours of the night when God isn't even awake anymore.
Point is he didn't need to do this, the manager at that store I dont expect to have in depth knowledge of every product in their shop, but at least should be up to date with the important stuff like hey we are selling stuff that will not exist in a month you get the point instead of solidly saying that untrue etc etc making me the client feel like a idiot instead of saying maybe " hey Im not so sure or aware of that, do you mind if we quickly go google this." Bamn! Everyone's happy.
Postmanpot you don't perhaps own a TV shop?
I would once support that shop. You have a gift!
