So if I was to order 10 units today, shipped to USA, how long would I wait approx to receive my untis?
It would seem on average 4 days, not including sunday. This is from the day you place your order, before 6:00 pm their time. Two days processing, two days shipping.
While you wait, buy everything else you need and have it all set up, waiting for them to arrive.
You will be happy.
