If you open a new Discover More credit card account now, you can earn $50 cash by spending $500 within the first three months of owning the card. The card also offers 1% cash back on all purchases in addition to 5% to 20% for purchases at select online stores.

This credit card is of the few still offering generous cash back as well as an introductory APR offer. With the Discover More Card, your purchases will be interest-free through June 2009 and your balance transfers will be interest-free through December 2009. Pay attention to the details of this offer so you won’t lose this benefit.

If you are interested in opening a new brokerage account, you will now have more time to qualify for TradeKing’s $50 new account bonus. The promotion was originally slated to end this week, but the brokerage has decided to extend the $50 bonus through November.

In order to qualify, open a new account at TradeKing using a link within this post, fund the account with $2,500 within 30 days (you can leave your money in the default money market fund if you’re not ready to delve into stocks), and trade at least once within 180 days. Trades are relatively inexpensive at $4.95 each. There are only a few discount brokerages that offer trades at lower prices.

When you visit TradeKing’s application, make sure you see this icon in the top right of the screen. This is how you can verify whether you are offered the $50 bonus.

SmartMoney rated TradeKing the best brokerage in customer satisfaction this year.

If you own a credit card from Bank of America, the bank is offering you a $75 bonus for opening a checking account with a minimum deposit of $25 before November 30. The bonus is available for Bank of America’s “MyAccess” checking account.

To qualify for the bonus, visit Bank of America’s website, select the option to open an account, select your state, and select the free MyAccess checking account. After confirming whether you are a current customer, you will be presented with the opportunity to enter an offer code. Use CH75EM1 to qualify for the $75 bonus.

If you have experience with Bank of America’s banking services, please share any stories. I do not have a bank account there nor do I have a Bank of America credit card.

Note: As of October 28, this deal is no longer available.

This is just a quick reminder that the promotion for the $25 bonus offered by E*TRADE Bank ends today. In order to qualify for the $25, you must open your account by today and fund the account with at least $5,000 by Monday, November 10.

A number of people reported that referral bonuses offered by E*TRADE Bank pay $25 and have no minimum balance requirement. If you can find someone to refer you, that is definitely a better deal. However, if you plan on keeping $5,000 at E*TRADE anyway, these two promotions offer the same benefit. Here are further details and here is the application.

As of today, ING Direct is offering a 2.75% APY on the online bank’s Orange Savings Account. They are also offering $25 account opening bonuses to new customers with an initial deposit of $250 to qualify. This bonus is based on a customer referral; existing customers receive a $10 bonus for referring a new customer who receives the $25 bonus.

I’ve been a customer of ING Direct since 2003, and I’ve earned over $500 by referring customers throughout the years. I have no referrals left, but I’ve opened up an offer to Consumerism Commentary readers. Existing customers can request to be added to the waiting list (when it is open—it is not right now) and in turn, readers’ referral codes are posted on Consumerism Commentary for use by new customers.

Tonight, I refreshed the list of available $25 ING Direct referral links. If you would like to open a savings account at ING Direct and you have $250 for an initial deposit, please consider using one of these links to benefit other Consumerism Commentary readers.

Once you are a customer, you should receive your own referral links. You can then share those links on Consumerism Commentary (once the waiting list is open) and your friends and family to earn up to $500 in addition to your $25 account opening bonus.

If you don’t have $250 for an initial deposit, just click on the above graphic. You won’t earn the $25 bonus but you’ll still be granted referral codes of your own. If you do have $250, earn an additional $25 right away by choosing a referral link.
