Web Monkey, you obviously skipped over the 'exact same' part of my post. So if your sushi/burger was cooked 3 day previously, had 1/3 lbs meat slab on it, lettuce, tomato, mayo... ect ect... then the other store would to.
My point wasn't about buying food based on price, it was about buying IDENTICAL products at 2 extremely different prices in most circumstances.
Again, i'm an extreme newbie to scuba diving, so maybe i'm overlooking the benefits of buying from a shop...
But i've only heard really 2 arguments....
1) You are stealing the business's time.
Well, I own a Server Rental company aside from what i do daily. Basically, I have setup servers previously as 'test runs' for FREE. I've had to, at numerous points, work to sell my stuff. Most people look at price, then they look at quality based on the price. If I want to get my servers sold, i have to have prices that beat almost everybody else. And to keep customers, i have to make sure they stay happy by helping them with any issues that might come up. That is the way every business is. If people want my business, they should have to work for it.
2) Warranties
This is probably really where I agree with a lot of people. I have, however, bought numerous things off the internet, including computer hardware, ect. I've had things break and have had to return packages from where I bought it, ect.
There are downsides to buying online, but 9 times out 10, if you are careful where you buy and buy from a well-known online website, you will get what you pay for... whatever that might be.
