I depot everything. Shadows, duos, blushes.
It's just easier for me because everything is organized and right there in front of me. Even when they were organized as singles, it was still difficult because I have to keep everything in order all the time and things can get misplaced.
De-potting a shadow only takes me around 30 seconds and I haven't anything damaged so it's just the best option for me.
Oh yeah, the counters I go to have no issues with accepting de-potted B2M so getting the free stuff is awesome.
