SO here is a great deal. You can either get free stuff or dicounted items with this $10 credit and free shipping. I just ordered a 55cm workout ball. It was priced at $9.98 in the hot deals section. There are also mixing bottles and jump ropes.
Here is what you do:
First Create an online account here..
Then go shopping.
Use code myOW2424 at checkout.
I did have to enter credit card info even though the total was $0.00. I used a giftcard/credit card and it went through fine.
