When it comes to nail polish, I have always believed you get what you pay for. From my experience with nail polish, the cheaper brands usually chip really easily and the colors are typically a bit blander than the more expensive brands. I found the Loreal brand nail polish at a drugstore in my area and fell in love with the colors. They didn't have a huge selection of colors but the ones they did have I really liked.
The price for this nail polish is on the lower end, costing about $5 per bottle. I figured that it would chip a bit but I was wrong. The color lasted on both my fingernails and my toe nails for a couple weeks. The only reason why it didn't last longer was because I changed up the colors.
I would recommend Loreal nail polish to anyone looking for an affordable nail color with an expensive looking color. I also should mention, when I go to the salon to get my manicure and pedicures, I also take this polish along with me. The polishes they typically use aren't that great of quality and I have a problem using polish that has touched another person's toes.
