I've been using this site to buy stuff for my girlfriend for over 2 years now. They've got a huge range that keeps growing and it's free international registered delivery (their distribution center is in Hong Kong). Their prices are almost always cheaper than the shops and any other internet shop and this becomes more evident with their specials. They've also got loyalty discounts and also a multiple buy discount, and you can always request samples for other products to come with your purchase.
The only thing I haven't tried to buy is perfume, which now comes with a surcharge and I haven't really compared their prices with the other places around the net or the shops.
StrawberryNet ALWAYS has free shipping for Skincare, Make Up, Body Lines. This is not really a time limited special.
