I love Juicy Couture Viva La Juicy. I always get complements when I wear it. That might be $65, though.
Vera Wang Princess is also nice, and I think that's $50-55. If you like vanilla scented things, the brand LaVanila sells perfume for about $50. They have plain vanilla and also difference vanilla mixes (vanilla coconut, vanilla lavender, etc).
First of all look on Amazon.com, they have good prices on perfumes. Often free shipping too. I got my Pink Sugar for 25 bucks, and I had a 20 dollar Amazon coupon, so I ended up paying less than 10 with taxes!
