			The LDS takes full responsibility for everything they sell. Air, Gear etc., when your Local Dive Shop is gone those of you who choose LP to save a few bucks will finally get it. In the long run you save nothing. The Local Dive Shop IS your Club. Social clubs tend to be loaded with politics. The Local Dive Shop should make you feel that you are a member not a target. So if your shop is not treating you right, then simply find one that will. Those guys at LP "DO NOT DIVE" and have no official relationship with the manufacturer. When I was on the other side of the counter, I treated my decisions to buy from my Local Dive Shop as if my life depended on it. 
A Dive Shop is a business and has to make a living. You do not have to blindly deal with just any dive shop. Search around for a shop that makes you feel comfortable, patronizes that shop and you should reap a multitude of dividends. Such as good advice far more valuable that a cheap price. Then dont be afraid to negotiate, after all the Dive Shop owner is a fellow diver and the good ones are friends.
		
		
	 
Unfortunately, not all of us have the luxury of "choosing between" LDS's.  We live in sunny Saskatoon, Saskatchewan Canada, it has 220,000+ people, and three dives clubs, but only a single LDS.  The fact that it calls itself "The Diving Centre" says something about the attitude of its owner.  He has sometimes been very helpful, esapecially on dives and dive boats, and that is greatly appreciated.  Unfortunately, he has also:
1) Strongly recommended gear *he sells*--like the floppy SP Twinjets he persuaded my daughter and I to buy (they're great for really casual diving, btw...but almost dangerously inefficient in current or emergencies.)  
2) Continued to have a very variable price structure...offering to meet or beat even internet prices, yet having sticker and website prices that are nuch higher
3) Surreptitiously gouging huge markups on such items as the stupid little Princeton "Vortec" headlamp which he sold me for $80 CAD, which fell  off my head in a night, cold water, curent dive, then fell appart on the dive skiff.  Or the--totally useless in the ocean--Airhammer he sold my wife for $130 CAD (I later noted that LP sells the light for $30US!)
4) Always seeming to blame the diver rather than the equipment, for example claiming that the tendency of the Mares Synchrotech Pro BC to drop its integrated weight systems of not using this BC properly. Other owners confirmed that the problem is also, even mainly with the design.  Another example is a SP G250 reg that he has tuned and fixed several times, that keeps having problems.
With three people to buy for, two of them new divers precious to me, I have had to go to the internet, eBay and MO to find safe, high quality equipment at prices we can manage.  Thus, I was able to get like new ATX 200's and Cobra computers and Ladyhawk BC's for them, and a used SP G250 and Cressi Archimede for myself for as total sum we could manage...and 30% to 60% less than his always variable pricing.
We did briefly look at the Cobras and his brochure on them, long before we found them from a closing dive shop and Divetank on the net , but I hardly feel guilty about this.  
We did buy nasks, snorkels, fins, bags and many smaller items at this LDS, and just this morning I cancelled an order with LP, on realizing that most of the items would be available from the LDS.  However, I also just received a couple of pairs of Apollo Pro XT fins with steel straps and a UK dive light from Divetank...the Apollo's being a line he doesn't carry and the light being 50% of his price.
The cautions about LP not being divers and occasionally selling real crap (avoid their gift packs, save-a-dive packages etc.) are right on the nose.  It is better to do to real divers. 
However, all the preaching about supporting the LDS is pious nonsense, if the LDS happens to be a monopoly with an attitude, which, however helpful at times, could also injure or kill you in its disregard for the reality that dive equipment--even the lines they sell--still is much less than perfect.
