The frequency of these leads me to think it's a glitch with FB. Normally, these wouldn't get repeated every hour like clockwork, they'd just go out once. So while we can certainly send our fair share of hate and blame toward ZG for having the unmitigated gall to want to reach out to his customers through his business's Facebook page, this isn't really his fault, it's something wrong with Facebook itself. Pretty sure it'll work itself out and stop soon enough.
ZG, I would start sifting through the FB Help Forums or try shooting a note to FB Tech Support directly to let them know of the issue (which I'm sure somebody with less patience than you has already reported a million times.) Maybe if you tell them how it's affecting your business (I know
I won't ever buy from you again because of this

), they might give you some free Farmville nails or something....
But really, folks - don't flick ZG too much crap - he's not the culprit here. You should have only received 1 email and instead you got several (so did I.) I know that it's super-difficult to hit that "delete" button more than once a day - especially with the old Compuserve email servers, but I know we can all get through this and emerge stronger because of it.
