The list will be endless, really. I buy almost everything on the internet and there are many reasons why. First of all, it's cheaper and saves time. Also, there is a wide choice in online stores, it plays the main role. Usually, I buy online shoes, clothes, books and vitamins (by the way, Canadian Pharmacy Online is a good and licensed online pharmacy).
I have been buying a lot of clothes online from GotApparel.com, for example. It is a really cool and helpful online supplier with such stuff, and I recommend that you will find it interesting and working, good luck with!
