Yes, multiple small parcels. Menlo Park Post Office. I built a couple of iSpindels and the components I ordered got split due to being from multiple vendors (aliexpress). So what should have been 2 packages (electronics and pc boards) ended up being six packages.
All were delivered to the Post Office at around a week between packages and all collected without issues. No losses, no damages, very friendly staff. Only thing that irked me is that I ended up paying six 'handling fees' instead of just two which increased the cost of the project.
Only to renew my car licence, and the line for this was about 15 people at any given time (people joining and leaving the queue). While in this queue, only 1 person came into the post office for something other then licence renewal.
