Remember, most of this stuff will be available after the Kickstarter is over.
well, yes and no.
With BT and CG as an established license and company the appearance of stuff post ks will be more reliable than with most start up ks where often enough their retail goals fall significantly short.
However for non US prices and availability might be a bit less favorable, in particular with regards to shipping.
edit:
just as an example: a Colonel would cost alone something around 55$ in VAT additional to any shipping, when ordering something of that value directly from the US. So the ~30$ shipping is a very good deal for that range.
Also, the pledges of better deals than any single retail mech box would.
the Colonel is at 3,8$ per mech (assuming 5 mechs per selection and pretending it's only mechs and ignoring all the other stuff)
Which makes the selection process a lot harder .... :)
which incidentally also caused the for CG problematic number of canon characters they have to deal with. When a pledge level is the best deal no matter what you are looking for then you get a lot of collateral characters. ;)
