Hi Jazzy - It's normal to be scared on the first shop. It will get better over time as you gain experience. Everything Flash said is good advice. It might help to practice the shop at home - what you plan to do and how you plan to cover all the information you need. If the store is real close to you and you have time, why not go by a day or two ahead and do a practice shop? Or, maybe you could even do a practice shop in a different store.
