I shop on Amazon all the time. I usually buy my items used. There's nothing like getting a book for a penny. Sure, I have to pay $3.99 for shipping, but I'll buy a book for a penny any day.
I like totally love Amazon, even though it's not as good as it used to be. I am going to check out their handmade section soon. I used to buy and sell on Etsy, but that has become a trading post for Chinese raw materials.
