Exchanging a product at Bath & Body Works?

I ordered 3 things on BathandBodyworks.com and I just got them today. I realized I didn't really like them so I want to take them to the store to exchange. What I got was a EDT. for $23.60, a body mist for $9.60 and a lotion for free in the same scent. It was a buy 2 get 1 free sale online, I used a 20% off plus free shipping coupon so if I exchange all 3 things in the store, can I get all 3 things in a different scent or what? The total of my order came to $35.00. Also, I still have the box for the EDT. and the paper that has all the prices and information on it.
