They do note that you may be required to pay the sales tax when you pay your yearly income tax. Here's the email from Newegg:

Dear Valued Newegg Customer,

As a result of recent changes in New York State tax law requiring certain out-of-state retailers to collect and remit sales taxes to theState of New York, we began collecting applicable sales tax for all orders shipped to New York addresses starting June 1, 2008.

After careful review and consideration, we are pleased to inform you that we have stopped collecting New York sales tax, effective August 21,2008. This decision was driven by your direct and candid feedback andour continued commitment to you as our valued customers.

We appreciate your patience as we worked through this process, and would like to reiterate our commitment in offering our customers the broadestproduct selection, competitive pricing, fastest shipping, and award-winning customer service.We look forward to continuing to provide you with the premier onlineshopping experience for all of your IT and consumer electronics needs.

Sincerely,
Bernard Luthi
