Hi Kobi,
That's a very valid concern, but of course that will depend on where the item is being sent, how the item is being sent and how long before the supplier send it, so it's impossible for me to give you an accurate answer. You can narrow down a guestimate by speaking to your supplier about their shipping times and methods used, but there are so many factors that can impact delivery times, you'll never get an absolute time, only an estimate.
