Profusion: Pro Face Professional Eye Kit
$13 at Target
I also purchased this one recently, as it is a new brand at Target, and I wanted to see if their products are any good. Let me tell you, for a $12 palette, I was really impressed with this product. It not only offers 20 shades of eyeshadow, but bronzers, blush, and highlighter, in addition to eyeshadow powder and wax. It actually has pretty darn good color payoff for being so inexpensive. I would definitely use an eyeshadow primer and some setting spray, as this product doesn't have a ton of staying power; but it definitely is a great deal for such a low price.
It is a hefty palette, being about an inch-and-a-half thick, but with all the products it replaces, you'll have plenty of extra room in your makeup bag. Plus, it comes with a blush and eyeshadow brush, and you could even slide a lip or eye pencil in the brush area to save on space.
Profusion also offers the Glam Face Makeup Case, and the Eye & Cheek Makeup Palette, which are great if you need something more compact.
