While flipping through my Costco coupon book tonight, I noticed that Sharebuilder is running another promotion with Costco:

You can get a $70 or $90 Costco Cash card (depending on your membership level) after opening a new account and making one trade. They seem to be buckling down against people opening multiple accounts for bonuses, as it is now “one per unique account holder”. If you don’t have a Costco membership, there is also a similar bonus offering a $50 account credit.

Note: I just noticed in the fine print that you shouldn’t open the Costco-related account until 9/4, as that is when the promotion starts. How annoying, just like these post-dated Costco coupons…

Now, unless you really want to use Sharebuilder ...
