Again as many know this is a peeve of mine,
why cut out your LDS? they fill your tanks and without them you can't dive. No getting air online.
Also, I read a recent post about a guy getting BCD online and guess what? Not authorized and he was SOL.
Many LDS will match or get close to online prices if you ask an they are reasonable. But even if I have to pay a bit more, isn't it worth the WEALTH of knowledge they share with me when I go in on current conditions, what they are seeing and do they recommend a great spot.
While there are some LDS that get under my skin by overcharging for basics like masks, major equipment is your lifeline and IMHO I want to make sure I come up alive, not in a bodybag from faulty equipment.
