Painting My Bathroom

I paid full price for a gallon of paint at Home Depot. I just hadn't considered there might be cheaper ways to get paint. I wanted a light to medium khaki color, but I wasn't too picky about what shade. I went to Sherwin Williams a few weeks later and discovered their Oops paints...for $3 a gallon! The paints are perfectly fine. An employee just messed up a little on mixing the color, so they aren't exactly what the customer ordered. They can't simply throw away paints, so they're sold for a fraction of the original price. I was shown a huge stack of neutral colored paints like the gallon I had recently bought.
I mentally kicked myself for not realizing this sooner, but oh well. I'll know better next time.
