I decided to purchase the sets so that I could try more of the brushes out at once. The sets usually run about $14-$18 depending on sales and where you purchase them from.
I must say that they live up to all I'd the hype I've heard! I really like that the sets come with their own brush holder/travel roll to make storage easy. In addition to that, you can fit extra brushes in the cases as well.
I ended up only spending $50 for all of my brushes with the 50% off deal. If anyone would like to see a full review please let me know.
