FWIW my son was recently certified at my LDS. We got his mask, snorkel, fins, boots there. After he was certified his instructor wrote him a thank you note for choosing thier dive shop etc. At the bottom of the note they wrote that if he was looking for a reg and BC and purchased it there they would give him the advanced OW class for free. I thought that was a real nice way to lead into a purchase with out the hard sales and offer something otherwise costly to offset any difference.
I recently purchase 4 items from them, the difference in the leisurepro price for the same items and theirs was $80. They have been there for me when I needed advice, dive buddies, air/nitrox fills, or as a local place to take more classes so in my mind that was worth it to spend a bit more there. I was talking to the owner there during my sons class and telling her about how my wet suit doesnt fit me since I gained some weight. She didn't try to sell me a new one but told me to bring it in and she might be able to let it out for me instead. To me thats the way a good dive shop should be run.
