Update April 2016. I originally wrote about this promotion in October 2013, and many readers have been getting $20 of interest every month on a relatively low balance (worked out to 16% APY on $1,500 average balance). With a 1% APY savings account, you’d need $24,000 to get the same amount of interest! Unfortunately, Santander Bank recently announced that this promotion will end and accounts will be converted to a Simply Right checking account later this year (reports include either July 1st or December 1st, 2016).
I would note that this deal lasted for over 2.5 years, longer than I thought it would. Just like with 5% APY Netspend prepaid cards, you can’t really predict how long deals will last. Some end earlier than you think, some end later. Don’t forget to close your account in July, unless you’ve gotten attached to your Santander account (which was always the idea!).
