Best Foundation for combination skin?

I am 26 years old and have combination skin so I find my makeup wears off on the oilier parts of my skin. I've been using revlon Colorstay foundation for oily/combination skin. Its okay but I want to try another brand. The only stores where I live are walmart, shoppers drug mart, sears and merle norman. I'm not ordering online, so products like MAC are out. Thanks
