The USA Senate voted on Thursday to pass a Federal sales tax legislation which will allow government to collect tax on purchases made over the Internet. However, a final vote got delayed until May after senators return from a weeklong vacation. One of the most affected party eBay has now started emailing millions of it's users as an unprecedented lobbying effort to pressurize government from passing the law. The email asks users to oppose the "Marketplace Fairness Act", by sending emails to members of Congress asking them it unfairly burdens small online merchants.
