I know this sounds silly but I LOVE shopping online. I actually do it 3+ times a week. I think I am addicted to getting items in the mail. I do small things, I never over order or waste all my money.
There is nothing wrong with shopping when you are not addicted to it. I have a friend who is such a savvy shopper that she can get triple the amount of stuff at half the cost.
I have a bit of an online shopping addiction when it comes to food. lol
