Oof, that Ghost Ramp sale is frustrating. I wouldn't have preordered stuff if I knew I could get 25% off by waiting before it's even out; that's like $30 saved.
I tweeted at them but I guess I should go email as well and hope I get a response.
FWIW I did that with a previous order and they applied the discount no problem. They've always been super helpful with stuff like that.
