Today I received a cashback check of $61.54 from Upromise.com. I have been using Upromise service since August 2003. Upromise is a useful service that helps people to save thru grocery shoping, online purchase, dining and a number of other activities.
Its service is generally hassle-free: you only need to register your credit card number and grocery card number to be eligible for offline purchase rewards, and you can be entitled to online savings by going to online merchants thru Upromise web site.
The default way to cash out your accumulated savings in Upromise.com is thru its affiliated 529 plans, but by sending a snail mail to Upromise you can receive the rewards in checks like I did.
Citi also offers an Upromise credit card that offers more benefits. (Read: PFBlog review of Citi Upromise card.)
