No worries Pete!
if someone doesn't think its for them, then no big deal and they can move

That's the beauty of capitalism: we can make free choices and there are so
many of them to make, and those who try to sell the wrong, or overpriced
goods/services (hopefully) go out of business eventually.
Bye,
Said
