Some of these hops are going to be difficult to come by this year. If I read the promotion correctly, one notable homebrew shop will not be providing Simcoe and Citra this year. They gave away their entire stock as a promotion because they did not receive enough.
For this year, I'd recommend picking up hops sooner rather than later.
