Free is Not Free Enough?

I just read an interesting article discussing "Just When is 'Free' is not free enough!". <-- You can read the article.  At first, I was a little taken aback by the title. My first thoughts were, What? Free is Free! Waiting for it to go on sale? *Puzzled look on my face*

 After reading the article, I had a DUH! moment. Of course, I do this! I wait for Free enough to score another very cheap product, or if I get lucky two free products. Now, you may ask, Jennifer, How is that possible? How can you get two free products with a free product coupon?

Well, you can always wait to see if a really good sale is going to happen for the particular product. For instance, I had this happen to me a few weeks ago.

I had a free Herbal Ecessence Coupon. I then found a sale going on for BOGO (buy one get one) and scored 2 free Herbal Ecessence products! Sweet!!!

 I really like what was stated in the article I read. Good things come to people who wait! It sure does in the couponing world! I have a pretty descent stockpile (no, nothing compared to the "Extreme Couponers") and I have scored a huge chunk of my stockpile from waiting for FREE ENOUGH!

One thing to keep in mind tho, don't wait so long you don't use the coupon by it's expiration date. Yes I am guilty of this and ended up not so happy.

 So, my question to you is: When is Free not FREE ENOUGH for you? Thoughts?
