One thing that I think LDS's could use to distinguish themselves but often do not is knowledge about products and working / talking with a customer to understand what will work best for them. All too often the internet is filled with conflicting information and opinions set out as fact. As a relatively new diver, it was very difficult for me to sort out all of the noise and such to understand what would work for me personally. Unfortunately, most of my LDS options are typically staffed by folks who don't really understand what they are selling or how to guide potential customers thru the considerations to decide what works for them. You often get a "well, people seem to like this one..." or the automatic pointing to the most expensive one and when you try to ask why that one is better for you, you get blank looks.
I would have happily spent more for the opportunity to talk with someone who truly knew the a lot about the various options and could have helped me through the process. I don't want someone just telling me what is best with no explination, I want to understand what the considerations are and what that may mean to me. After all, in diving this could mean my life or, at least, comfort and enjoyment of the sport.
I wish LSD's would realize that they don't need to beat the online retailers at their own game (price), they already have a built in advantage and that is that they actually have the opportunity to directly deal with their customer that may, over their diving career, spend thousands of dollars at their store. This starts the moment they have someone sign up for a new class.
I think this kind of knowledge and support will build in loyalty and if I consistently received such guidance/information from an LDS, I would be willing to pay more, not ridiculously more but would value this. Yes, there will always be those that would take the information and then go find the cheapest online price but you can't win them all.
I realize that this takes a lot of effort on the part of the LDS to keep it's staff up to speed on all the new equipment and technology but I don't see the effort and more often see very attractive but useless sales staff or those who don't take the time to understand/question you but are just pushing the one they think is the best.
