Hmmm... I don't have too many backups, because I hardly ever finish stuff-- but I do have a few!
Firespot e/s--1
Ardor slimshine--1
Don't Be Shy blush--2
Blot Powder--2 (because sometimes my store sells out)
Moisturecover concealer--1, just in case

I *think* that's it... but I'm not so good at organizing extras, so there may be more!
