Tupperware and rest of the business world

Where as the aim of every business in the world is to use every means available to popularize its product and sell more Tupperware seems to be sticking to its stand and using only direct marketing as its only selling mode. I was surprised to read that they are resistant to internet and consultant is not permitted to maintain a website that promotes their Tupperware business, nor may they use any third party website such as eBay or amazon to sell Tupperware products.

They may also not undertake any advertising or publicity using the Tupperware name without the specific permission of the corporation, which sees such advertising as as trademark infringement. In practice, these policies primarily limits consultants to word of mouth advertising through the party plan.
