I’ll make one other point... There are 2 different marketing schemes in use today.
The first is called MARP (Manufacturer Authorized Retail Price) this is when the manufacturer tells the retailer what the minimum price an item can sell for. This goes against the free market system. It is price fixing and keep the price of the product artificially higher than it otherwise would be. ScubaPro, Aqua Lung are such companies and although the products are quality IMHO it isn’t worth the extra you are required to pay.
The second scheme is called MAP (Manufacturer Advertised Price) it sets the price the retailer can advertise an item for but the Retailer is still free to sell for any price. They can compete for your business with discounts and markdowns as they see fit. This benefits us all with lower pricing and the best gear competing fairly in the open market. The majority of Manufacturers play fair and use this system.
With this in mind It is my suggestion that you be aware of the fact and vote with your purchases for MAP manufacturers and avoid MARP pricing.
