Someone suggested this site --- said that she had gotten good results here. The site certainly has quite an assortment and prices look a little better than I've seen but I don't know if the shipping costs would cancel any savings.

Here's one that I have used. It has free shipping. Strawberry.net

This is a good site, the free shipping is definitely a bonus and the prices are good. However, I wear 'Fidji' by Guy Laroche and the price quoted on the site is £17.70 . I can buy this at £14.99 for a 30ml spray in a department store in my nearest town. Sometimes it is worth looking around the shops.
