flash sale

I get a lot of spam mail. Except a lot of the time they are sales, and I do love a good sale. The worst are the flash sales. I feel like "OH! I gotta check it out! I'll totally miss out!" and then spent forever combing through trying to find something worth buying. If I do, I then re-scour trying to find more to make it worth ordering. Usually it isn't the type of sale I hope for and they don't have what I am looking for and I'm disappointed.
