Buy 1 Get 1 For 1/2 OFF

I found some Jojoba oil on sale today!  I stopped by GNC today in hopes of nabbing a bottle of jojoba oil.  It has truly become a new staple of mines.  I always add it to oil mixtures, however lately I've been placing it under my gel on wash day, braiding out with it, and using it as a sealant after spraying my hair with water and oil in the morning.   When I ran out of my trusted jojoba oil on yesterday I knew that I needed to replenish my stash.  Anyways, I stopped by GNC and grabbed the 4oz. bottle.  It's actually the only size that they sell at the store that I went to today.  It was actually $9.99, which to me is expensive for 4 oz. of an oil that I've grown fund of on a daily basis.  I headed to the register and started to check out.  The cashier asked if that was all that I was buying.  I said yes that's it for me today.  He then said, you didn't want to take advantage of buy one get one 1/2 off.  My response was "Well yeah!!!"  I love a deal.  I ran and grabbed another bottle of jojoba oil.  I'm happy that I have 8 ozs. of jojoba, and my hair is happy also!  Cheers to buy 1 get 1 for 1/2 off deals, unless it's buy 1 get 1 free of course.

Have you found any unexpected deals on natural hair products lately?  If so which product was it and what was the cost?
