I just got two packages, one from Redwolf valued at about $350, and one from UN Company valued at about $310. The charge on the Redwolf Package was $40; the charge on the UN Company Package was $70. Both were shipped by the same carrier, Speedpost, I believe.
Like the rest said, be ready to pay up to 30% extra, and if you end up paying much less, it's a bonus.
It's all fun and games until someone gets hurt...and then it becomes sport!
