Yeah, I made a large purchase of hop-ups from RCMart and even though the shipping was $20 the whole purchase was still cheaper than anywhere else I have seen. It was only a couple days [maybe 2-3] slower than Tower: pretty good for overseas.

Definitely recommend them.

EDIT: I don't remember the weight of the package but it had a battery, slipper clutch set, an aluminum shock set, a Turnbuckle set, and a couple of other aluminum parts so it wasn't light.
