L'Oreal Bare Natural Eye Liners and Powders were 75% off putting it in the $2-$3 range.
-$1 off L'Oreal Cosmetic 6/20 RP
These would make great filler items as well, so you don't lose any ECB:
Scotch pop up and classic tape dispensers were $0.25-$0.50.
-$1 off Scotch pop up printable makes it .50-.75 MM
Greenworks glass cleaner was $0.75. I don't think there are any coupons out there though, unless you've got one that hasn't expired.
**I just found a .75 off coupon for 1 Greenworks product in the July All You magazine! That makes this FREE!
