I have heard from at least half a dozen of you that I got the shipping wrong. That tells me that at least half a dozen of you did not read my initial post, where I talked about why shipping was cheaper for this Boom. Fer shame, fer shame... (In my best Gomer accent, LOL.)
Those who are in both groups and want tol take advantage of combined return shipping of their blocks, plan on the $14 box. If I can somehow fit your blocks from two groups into one envelope, I will, and will refund the extra for the box. But probably not. Remember this involves finishing both groups in time for the 2 month deadline, and then waiting for the 3 month deadline to get blocks back. But that's your most economical option if you are in both groups. You can do separate shipping if you don't mind paying for it. ( I hate that shipping costs so much these days.)
