You're in the drawing! (and if you don't win, there's enough people out there, plus a Tumblr mentioned in the comments here where people post codes that you can probably find one on your f-list or somewhere.)
The snacks are about a handful or a little more, yes. The pictures on the website make them seem bigger, and I've found several photos on the site where they overfill the little containers they come in for the picture, to make it seem like more. In this one, for example, their food stylist has carefully posed everything, and overfilled the containers. The FAQ on box size for British customers says:
Yes! We've redesigned our packaging so that your graze box will always be the same size (23cm × 17cm × 2.5cm) so it should fit through most standard letterboxes. The boxes are just a bit bigger than A5 size.
and I think it's about that size on this side of the pond.
As for the snack containers themselves, Google Images to the rescue! You can get a rough idea of their size since you know the box size.
