I know of a few sellers who do Millions per year off Ebay.
Can't be stopped by Ebay? Ebay, PayPal, and Amazon can stop anyone, anytime.
It's their website, their Terms of Service.
Creating a LARGE busines on any 3rd party site is a recipe for disaster.
YOU have no control. They can screw you in a heartbeat.
I know many Affiliate Marketers who were pulling down over $40,000 month via Google Adwords. Then about a year ago Google stopped all affiliate sales. NO notice given.
I know of someone who has been selling via Amazon making $30,000 per month. Then Amazon stopped allowing affiliates in his home state. Now he is trying to rebuild.
If you do NOT control your Traffic and the TOS then you are at the mercy of the 3rd party site you are using.  |
