Needing to get legal documents safely and as fast as possible from UK to Thailand, I dropped them into W H Smith's on a Tuesday morning, they were collected later that day and delivered to my daughter's workplace late on Thursday! The return was just as good: 2 days flat despite a "mechanical failure" which delayed departure from Mumbai. Not so delayed that I'd notice! Collected in Bangkok on Tuesday morning and delivered to my door on Thursday at 08.30. Brilliant service and I would certainly use them again.
