 - **Stabilizers:** $20 - go get those TX AP, Durock, etc stabs! Your board should feel good
 - **Any other parts:** pitch me first - this is for stuff like rubber gaskets, dampening foam, etc.
 
+These are hard limits unless there's a very specific exception. You cannot take a grant from one part and move it to another.
 
 For the **MCU**, you have 2 options:

+The grant should be used ONLY for parts that directly go towards the *function* of your hackpad. This means cheapest shipping, no ENIG, no USB-C cables, etc. Hack Club is stil a financially constrained nonprofit and every bit of money we can save with Hackpad goes towards future programs.
+
+I added the grant because I want to allow *all* of you to be as creative as possible, but if the grant gets unnecessarily spent then I'll have to limit parts again in the future.
