Instead of getting paid back in cash for reimbursements, you can choose to get paid in any of your top five favorite stocks.

We encourage everyone to focus on the long-term benefits of investing, and contributing to their portfolio in a diverse and frequent way. NO FEES: We take $0 commission on stock / ETF trading and payments. There will be no fees regardless of the dollar ($) amount transacted or invested.
