yeahhh, i'd rather not wait till May of this year for them to arrive, I may go the BBTS route for the extra $15 and get them now.
Ah but you just asked where was cheapest, you didn't say anything about getting them in a decent amount of time.
In that case go anywhere else, every NA site follows BBTS pricing unfortunately. Lesson learned, jump on the $15 shipped preorder right away. I am already enjoying mine and I paid a total of $30 (man these things are prices so so right) We now know the first two rock in terms of look and quality (you need to get over the size though) so the last 6 should be just as awesome.
I'm curious as to whether the price increase to $18 shipped will carry over to the next batch of minis or not.
