What a cool idea! I have never seen one of these duo curler/straighteners before and I think it's such a great concept. If you hurry over to Amazon you can pick up this Berta 2 in 1 Hair Curler & Hair Straightener on lightning deal $13 (reg $27)! Plus, it ships free with your order of $35+ or with Amazon Prime.
In case you missed them, here are a few of my previous beauty deals from Amazon:
Amope Pedi Perfect Pedicure Sets $29 (reg $70) - just clip the $15 coupon to save an extra $15 off the sale price
Conair Compact 1875 Watt Folding Handle Hair Dryer $15 (reg $17)
