Some of the items they're offering are:
1. Free Sultra Flat Iron with the Purchase of Sultra Hairdryer. The Flat Iron by itself is a $115 value! That's almost a 100% buy one get one free. AWESOME!
Blue Copper Firming Elasticity,
Osmotics Cosmeceuticals Blue Copper 5 Prime, 1.7 oz, or Osmotics Cosmeceuticals Blue Copper 5 Molecular Repair Treatment. That's a $75 value! Again, Amazon craziness at almost a 100% buy one get one free value!
Pink Sugar Eau de Toilette Natural Spray, Pink, 3.4 fl. oz. We know, we know! It's a little girly and sweet but, it's truly a classic scent that keeps us going back for more. Also, that's a $20 value for a $60 purchase.
In terms of percentage back most of Amazon's offerings are at least 30% of the value of the item you're purchasing. But, as you can see above, there are several that are almost 100% of the value of the item you have to purchase. It's just insanity!
