Northeastwrecks once bubbled...
While I don't disagree that there are less expensive sources of gear, I wonder how much you lose in terms of convenience and how much cash you spend on other items.
I buy 99% of my gear from my LDS. The 1% I don't get there is because its specialty gear for which there is almost no market (all graphite pencils, a custom computer strap).

As a shop AI, I don't pay for gas, including technical mixes with high O2. I also have access to the fill station pretty much around the clock. I also have an account and can sign for items even when the shop is closed. In exchange, the LDS prefers that I use their equipment, although they don't require it.
Even customers who are not on staff do well at this shop. The LDS has (1) added product lines when we requested them (DUI and Halcyon are the most recent); (2) a long standing 100 day return policy on gear; (3) awarded credits against class costs if you buy your equipment there.
Finally, the LDS provides perks to regular customers. Buy your entire rig and the LDS will throw in some accessories, in addition to giving you a volume discount. Buy a drysuit and get a class on its use. I offer my EFR students very nice first aid kits for cost when they complete the course.
The final benefit is that I can dive much more regularly than I would if I were not using the shop. I'm a member of a regular dive team that operates out of that shop. No buddy horror stories, no other problems and a great group of people that uses the back room of the shop as a clubhouse when we are not teaching. We travel together and have great luck with dive operations because we take over all or most of the boat.
We get this type of service because we support the LDS.
There's no question that we pay more for the service. However, I'd rather pay more for a premium service than spend my time kvetching about my awful LDS.
Besides, I figure that, between air fills, free samples, fast repairs, discounts, training, etc..., I've made out fairly well. It all contributes to stress free diving, which is far more valuable than the money I'd save shopping my business.
