Unfortunately, consumers are used to fast deliveries. I am aware that for a family business that might not be a realistic expectation, and also shouldn't be. To tackle this, it might be good to mention on the website (redundantly) and in the "order confirmed" email that people might have to wait x number of days before getting the next update on their order. That way, there are no false expectations.
When I asked about my expected delivery date in email, I received a quick reply. Thanks!
