Quantity vs Quality

I am a nail polish junkie. I'll be the first to admit it. It's a lifelong obsession. That being said, I've used up countless bottles and have learned what works best for me, OPI.  Although, being $8 a bottle puts a damper on things.  So, every once in a while I cheat. Meaning I buy other brands, less expensive brands just so I can have many different choices in color.  As my husband reminds me, it's all reds and pinks, but none the less- choices! Of course, I always regret it after the next day and the mani has already chipped.

Which brings me to the question- quantity vs quality?
