Is every business idea good for the web?

Although the .com industry is really shaking out, it seems that the e-commerce sites that are thriving offer their products at an excellent value. After all, the client is loosing the ability to pick up the product, turn it over, kick the tires, etc. If they don't like it, they have to send it back to you or be stuck with 'buyer's remorse.' In exchange for that flexibility, the buyer expects value. The sites that are succeeding in e-commerce give the buyer excellent value.
