I really like the Goody Spin Pins and the Sally knock-offs aren't cheap enough for me to cross over.
You're right, the difference in cost is minute. But Goody Spin is so popular, often it's sold out, so this makes Sally's a good alternative. That's what I like about Sally's doing the knock-offs, if you can't get your hands on the original, Sally's will suffice, until you can.
mg1979- Thanks. The bun is great when I need my hair out of the way, or my planned hair-do is a fail.
Chromia- Thank You. I'm waiting for Sally's to do a knock-off to the Kinky-Curly Custard or the Shea Moisture Coconut-Hibiscus Smoothie. I don't believe that Sally's has done any knock-off butters.
