Sure buff, buying online is a great way to go if you don't mind putting your local dive shop out of business. I have yet to find a place to get a convenient air fill online. Also as mentioned before, you can't expect a local dive shop to match internet prices. Most manufacturers won't allow an authorized dealer to set retail prices that low. Even if they were allowed to, the difference in the amount of gear sold in all but the largest cities would make a business go under. It's real easy to think your local dive shop is ripping you off until you've seen their books. For most shop owners like small farmers, it's a labor of love, not of high profit.
The bottom line is that buying online will save you several hundred dollars now but you can't pretend there aren't long term consequences for both you as an individual diver and for your local dive community.
