I bought every single piece of my equipment from my LDS because they took the time to talk with me about every single item, the pros and cons, other alternatives, and which they preferred. I got to try stuff on and see and touch all of the other similar items from its competitors. They know me by my first name when I walk in the front door at the LDS now, they know my child's name and ask about my life and how my recent trips have gone. They have always given me at least 10% off of my purchases, no matter how big or small. I have even received some items completely free, most notable a $300 Stahlsac travel bag and I can't remember the last time I had to pay for mask scrub or BC Life.
I buy from my LDS because it supports the local economy, because it puts food on the plates of families of those locally who share the same interests as me. We have a relationship now and I know if there is ever a warranty issue or even random self-induced damage that they have my back and best interests at heart and will do their best to take care of me. I like my free air fills and free weights when I need extra and I know that they can get me whatever I want and I will actually get to see it and touch it before I have to shell out a dime. It's all about customer service these days and I get it locally so why go anywhere else.
