This topic is always entertaining.
We have the LDS supporters come out of the woodwork to tell us how their LDS prices is as low as anything online. Maybe so, but it that was true to any significant degree overall we wouldn't be having this discussion. Most people's first contact with scuba was at the LDS (OW class). They were the shop's customer to keep or to lose.
We have those telling us how the online dealer has less overhead, carries less inventory, doesn't have store rent, or pay employees, and somehow doesn't pay taxes. Complete nonsense. Individuals may operate out of their garage but most all the big names that are mentioned here have physical stores - they are an LDS. As the discussion over whether Divers Supply was small or large pointed out, their overhead far exceeds most LDS. We've had some of the bigger online owners here describe in details their costs so I don't know why this point is even up for discussion.
My first loyalty is to my family. If I feel the need to write a charity check, I'll write it to my church or ACS or Red Cross, not my LDS owner. If he's really my friend, he should sell to me for less than some online place. Business IS business, and it doesn't mean "sending it overseas". BTW, can somebody tell me whose loyalty-based localized economy is doing better than our "toilet" economy?
As for having to ship things back for return/exchange/service, that's less trouble and often less expensive that spending gas money and fighting traffic to get to the LDS.
As for socializing, join a dive club. Much nicer to hang out with guys who aren't trying to make a buck from you, with guys who dive with you because they simply want to not because they want to do business with you, with guys who let you try their stuff out and give you honest advice with no vested interest.
I'm sure some of you really have a great LDS which you pass by every day going to work, who matches or approaches online prices, who does prompt onsite repairs, who has great people working there, and who serves as a social center for your diving community. But you all seem unable to comprehend that such is not the case for most of us.
