Let’s break it down.
Although trading over the Internet is often seen as a more informal way of doing business, the same rules apply as with the formation of other types of contract. The issue can be confused by the fact that in e-commerce the trader and customer are never face-to-face and are sometimes in different countries.
After many requests I have found some excellent sources for e-commerce contracts and information. I have read and reviewed the following sites:

SPECIAL NOTE: When in doubt consult your business attorney or your local chapter of “www.score.org”. They can give you some free advice. In the end of it all, make sure the contract is realistic and legible. Don’t scare away a potential partner with twenty pages of old english!
