Signed up in 2002 accrued 275 bucks by 2003. Started to save again after getting the Sallie Mae email about it in August, saved 150 since August. Rebates auto transfer on a quarterly basis - 400 just transfered to Sallie Mae on the 16th of March.
Keys:
Go to the grocery section, search for participating stores. Sign up all participating grocery store savings cards or CVS card - remember though to look for the Upromise savings sticker on your store shelves, only certain items qualify - i used to buy onsale, in bulk to maximize savings - add the grocery cards of friends and family to your account (my younger sister has my mom's, hers, and her inlaws store savings cards on her account).
If you can do without instant gratification, shop online through Upromise links - rebates range from 1 to 25% - lots of major online merchants. Since DH and I moved to AK, literally all our shopping is online - so its maximized our savings. Unfortunately Amazon.com isn't a contributing merchant. Using the Upromise toolbar will remind you to login for savings and auto authenticate you without having to actually "go" to Upromise first. We shop at Starbucksstore, Sephora, B&N, sierra trading post, chefs, giftcertificates dot com, ebay, florists, eddie bauer, target, walmart, priceline, etc. Eddie Bauer and Sharper Image gives rebates online and in retail stores.
If you have netflix or gamefly, or you are soon thinking about joining. Join (or rejoin with another CC) through Upromise and get 12 bucks (netflix) or 6 bucks (gamefly) in a one time rebate.
Sign up for erewards through Upromise. Only one erewards membership is valid per Upromise account. You will be sent surveys to complete. They'll reward you .50 to 20 survey points that you can turn into rebate dollars 20 points = 5 dollars, 50pts=20, 100pts=50 dollars. You can turn in once per quarter. I have made 88 points this quarter - hoping to hit 100 so that I can get 50 bucks this quarter instead of next. DH signed up for Upromise so that he could do the erewards and save for his own SLs.
If you subscribe to magazines - go to magazines.com using the toolbar or through Upromise's account and you get a 25% rebate on what you spend.
Every few months they run bonuses - right now select merchants are adding a few more % to the rebates they pay.
Upromise Mastercard - 1% rebate on all purchases; an additional 10% on participating grocery items (usually 1-3%), and 10% at on dining purchases at participating restaurants. I don't have one of these yet - hopefully I will get one to maximize savings.
When we sell our home and buy a new one, we'll use the Upromise service if its still avail. You'll get up to 3k rebate on one. My sister just got 3k for buying her house through a participating realtor.
Get insurance quotes for $2 rebate every quarter when going to insurance dot com via the Upromise website (or using the toolbar). No purchase necessary.
All of our CCs & debit cards are signed up so that regardless of which card we use to rent a car, we'll get a rebate. We'll purchase giftcertificates from giftcertificate dot com for stores we know we'll buy from get the rebate for that purchase, then use the certificate at the online merchant to get 'double' savings right now. Purchasing gift certificates directly from online retailers usually doesn't qualify.
Rebates post on average 40 days for online purchases, within a week for grocery store purchases.
If you have Exxon or Mobil where you live - they pay 1cent per gallon you purchase (minimum gallon purchase required every month - 30 gal i think). This one may or may not be worth it depending on how the prices here compare with other gas stations in your area.
If you have AMEX rewards, you can turn points in for Upromise rewards.
Just a few ways to earn $$$ to pay for SLs. I don't know (will probably ask the next time I'm on the phone with Upromise), but expect that you'll get a 1099 for the income at the end of the year. If this doesn't happen, I may consider trying to open up a few more Upromise IDs to save for me so I can sign up for more erewards accounts - i like doing surveys
