Get a signup bonus with Sharebuilder

Sharebuilder is offering a signup deal (not an affliate link) where they give you $50 and a copy of the generic sounding "Guide to long-term investing with Stocks and ETFs". Still, $50 isn't chump change. You need to deposit $50, make one share purchase, and wait 4-6 weeks to get your bonus. There are no minimums, no inactivity feeds, transaction fee is only $4, and you don’t have to buy whole stocks.

You can get get a little bit better deal if you are a Costco member. Executive Members get $85 (plus 25% rebate on fees) and Gold Star/Business members get $65 (plus 10% rebate).
