Everyone's experience will differ, of course; but I ordered a custom-build 13" MacBook Pro on 27 May 2020 and it was delivered to my home in the UK on 3 June. That included a couple of days going round a finance approval loop. Processing the order in China took from 29 May to 31 May, then there was a departure scan from the manufacturing facility on 1 June at 3am. The package then went from Shanghai to South Korea, Anchorage, Cologne and finally to Stanford-le-Hope in Essex, UK, from where it was delivered to me on the morning of 3 June. There's actually an extra day in there - the China/South Korea element of the journey is the other side of the International Date Line - the package left South Korea on 1 June and arrived in Anchorage on 31 May.
