"Today I have a review for you, but I also have a great deal on said product. What I have for review today is the Energizer XP4001 4000 mAh Universal Portable Charger which normally sells for $49.99, but it’s on sale for $29.99 but to sweeten the deal I’ve got a code that gives you $20 off bring the price to only $9.99. I added to my cart, using the code and with shipping it was only $15.99 shipped. So it’s obviously a universal charger, but it’s one of the better ones I’ve seen and as a bonus when you register your product you’ll be eligible for two free tips per year for life! Yes that’s for life, forever, every year you can get two tips. So read on to learn more about the XP4001 and see the very end of the review for the code so you can get that $20 discount. "
