There is another deal site now, KGB Deals.
If you sign up for their newsletter, and go to Philadelphia > Other Deals, there is a deal for a Sweet Cut Haircut, Blowout and Mini-Mani for only $15 ($34.90 value). This would be an extra special treat for a little one, albeit a short (1 hour drive) from Lancaster area.
Sweet & Sassy is located in Exton, PA or Cherry Hill, NJ.
