I truly have never been in one that after leaving I thought that shop had my best interests at heart, butbased on some here who work in or own one, I know that they do exist.
True story. Last season in a shop where we hunted some guy walked in and said something about being new to bow hunting and had seen a deer sign in the woods. He asked what he should do. Almost a dozen products later he headed out with enough stink to scent 100 acres.

It was the same shop that sold my brother a string almost2"'s too long and told him that the Hoyt recommended string length was wrong. He was stuck away from home and had no other choice. I heard the story from him when we met back up.
Get educated. Figure out which one you want. Don't be afraid to make mistakes. Archery takes time, if you want instant gratification your in the wrong "sport" "life style" "addiction".
You can do it!
