You are very right WTWR!
It is smart strategically to take advantage of the sales while we have the chance.
After reading your post I immediately opened up B12 (full price), B13 and B14.
I’m now racing to make more permits in time to open up A14.
If I’m successful that’s a saving of 21 Expansion Permits/4 Explorers Permits.
Thanks to ReinierMamaWouter, WTWR and NorthWoods for all your great advice!
You all helped convince me it was the right decision to expand.
