ElectricZombie:Not so...depending on how you look at it. The LDS depends on repeat sales from their customer base. Each year BCs come out with a new gimmick and that's what the LDS promotes. They sell the idea of constantly upgrading your gear to follow marketing trends, etc. People feel the need to have the "latest and greatest" and this is what the LDS counts on. If a student buys a BP/Wing as their initial purchase, they will likely realize that they do not need this years new gimmick BC. The customer will stick with their BP/Wing setup and the LDS misses future sales. In the long run, the LDS looses those repeat sales because the customer realizes that he doesn't need or want whatever "flavor of the week" gear the LDS is hawking. The LDS makes a small amount on the inital BP/Wing purchase, but that's it. Depending on their dealer level and markup, the LDS probably isn't making enough money off the deal to be relevent. In the long run, the LDS doesn't make any money by selling the correct gear the first time around.
Thats the biggest bunch of hooey I've read in a long time. First a dive shop makes money selling a BP/Wing just like selling a BC or any other piece of gear. The convoluted theory that by selling a diver the wrong gear so he has to come back to you later to buy the right stuff is bad economics and poor business. I have been in this business full time for many years and have run shops and consulted for others and selling the right gear the first time works better, results in a happier more comfortable diver that dives more and therefore spends more money at your store and reccomends his friends and neighbors to come to your store for gear and classes. There are plenty of followup sales to a person with BP/wings set-up you just have to understand what you are selling.
