75 oz. Purex detergent for $3.97 on Amazon (LIMIT 3 PER ACCOUNT)

Amazon has got this 75 oz. Purex Natural Elements Liquid Laundry Detergent for $3.97.  That's just slightly over 5 cents per oz.   (Doing the math, that's like paying $2.65 for a 50 oz. bottle.)  Because of the super-low pricing, there is a limit of 3 per account.

This is an Amazon Add-On item, which means that it ships for free with a $25 minimum order (and its price counts towards that $25).  You can buy multiples of this item to help get you to your $25 minimum for free shipping.  (Other Amazon Add-On item deals can be found here.)
