Many companies use SmartPost as their standard/free shipping and it does have a longer transit time and Adam's is no exception.
SmartPost will normally take between 2 and 7 business days according to your location, where something is being shipped from, weather and availability to fit on a truck. When I am able to order with plenty of time to get the product, I select SmartPost since it doesn't matter when it gets to my house. If I need it quicker, then I select premium shipping and usually have the products within 3 business days. This is not just Adam's products, it is anything that I need from any business, the exception being Amazon where I have prime. I can't blame any company for using the most cost effective method for shipping as long as the client has an option to select a more expeditious manner if need be.
I can say that I have never selected premium shipping on a Mystery Box/Bucket, etc. I figured, that since I had no idea what I'd be getting anyway - there was no hurry in receiving it.
As for the shipping notice, yes it would be nice to consistently get notified when something is on the way from Adam's and few other companies I do business with.
