Query: Overcharge for Shipping!!!!

I was charged $33 to ship a $16 memory card! It went from VA to SC. The site said that one day shipping was $17. Please explain to me why would I pay $50 for a 4g card when I can go to the store and get one for $30 something! I wrote them and told them to cancel the order. Didn't happen. Okay so I will return it and get my money back. They do not refund shipping - which is my problem!!! buyer be aware!!!
