Do this now: register for Discover it and US Bank Cash+ bonus categories

Registration is open for the Discover it and US Bank Cash+ bonus categories for the fourth quarter of 2015.

Discover it

Sign into your Discover account and click here to register to earn 5% cash back on up to $1,500 in purchases made at "Amazon.com, Department Stores, and Clothing Stores" from October 1 to December 31, 2015.

Since I'm enrolled in the recent offer from Discover to double my cash back at the end of the 12-month promotion period, I'll be earning an effective 10% cash back on the $200 PIN-enabled Visa gift cards I plan to buy from Sears next month.

If you're involved in reselling, the offer is potentially even more lucrative, since you can make purchases at Sears through Discover's shopping portal for an easy double-dip.

US Bank Cash+

Click here and enter your card details to select your 2% (unlimited) and 5% (on up to $2,000 in purchases) cash back categories for any US Bank Cash+ cards you carry.

The 5% cash back categories for 2015 are not too exciting, but you can still make an easy $100 in cash back on up to $2,000 in Kiva loans each quarter.

Conclusion

Registration for the fourth quarter Citi Dividend Platinum Select bonus categories of "Best Buy and department stores," and the Chase Freedom bonus categories of "Amazon.com and more" opens September 15, 2015.

As always, be sure to register now, before you forget.
