Frugal vs. Cheap

I had to take the loss and purchase an air conditioner for my room. Last summer my ceiling fan broke and I just used a window fan, which didn't really work well but I was being cheap and didn't want to buy an air conditioner because the summer was almost over. Yesterday was the hottest day so far and it was unbearable in my room, I couldn't imagine spending the entire summer in those conditions. I did a few internet searches and found that my room only required about a 5,000 BTU air conditioner. Luckily Target had a 5,200 BTU air conditioner on sale for $79.99, I purchased it and I am no longer uncomfortable in my room. This lead me to start thinking about the difference between being frugal and being cheap. I think last year I was being frugal since the summer was about to end I just toughed it out without the air conditioner. If this summer I didn't purchase one then that would just be cheap. Being cheap is when you can afford something and need the item but you just don't purchase it because you don't want to spend the money. Being frugal is waiting to purchase the item, waiting for a sale, clipping coupons, or re-using/repairing an item. So here is the million dollar question: Are you frugal or just cheap?
