There were no straps in my store (Birmingham, UK) even though I was told they would have during my appointment to try the Apple Watch on. This is a good thing really as I'd like to them to release some more colours, particularly for the Sports bands and the Leather Loops.
Watch with a black sport band as I had a feeling additional bands would take some time to ship. I want to use and use the black sport band for everyday use and I have a blue leather loop and Milanese loop on preorder for special or formal occasions. I'm glad I did now as my other bands still haven't shipped and it's no telling when they will.
