>>10601861For me the best freebees are the blank Crays. A whole little buddy, it's like an unplanned pregnancy!
I also like the Cappy Space Nii Stuff minis.
The worst are the build-a-stow-a-ways. I've made a lot of use with my blank Sincro legs, but the fact that even if you make multiple hundred dollar orders, there's no guarantee you can complete one without paying scalper tax is vexing.
Giving you accessory packs is probably the most clever option for them. I've gotten extra axis joints and phase arms in colors I didn't order, so if I make a following purchase I'll usually toss in some of those so I have an even number in that color.
