Greenhouse One is based out of Canada I think. When you order they forward the order to a supplier in China from what I hear. $13 for a 60ml bottle, price is good but you have to wait a month to get it.
That's the usual chinese timeline then! Great price though. I've had problems buying from the chinese websites ie quality, consistency, DOAs. I prefer to stay 'local' these days, a lot of the chinese vendors really don't save you so very much, particularly if there are problems.
