Woolworths has a bin of super cheap MUD polishes for $2! I got this one last time I HAD to go in a supermarket (I get my groceries delivered weekly), and was keen to find out what the formula was like.
Formula was thin, this is 3 coats. The other cheap brand in almost the same color is Ulta3 Purple Pumps and that needs only 2 coats. Stamped with China Glaze 2030 and Cheeky plates.
