When I see a low value card for a lot of points I just simply pass it by. The last 2 months I have received 6 $25 Wayfair e-cards for I think 57,000 points each and have put them to good use. With that plus the daily and weekly prizes I have won my AARP membership is paying for itself many many times over.
LOL, none of the extra credits have tickled my fancy yet, but you never know what'll pop up some day.
I did the extra activities last month, just for giggles, but I'll probably skip it this time.
There's another fun extra credit card, Dunkin Donuts, 12000 points for $3 value. Not much one can get for $3 at DD. Now if it were a $15 card (or even $13 for sake of an unusual value), THAT would be an extra credit.
The really fun part is that there is a regular (non-extra credit) Dunkin Donuts card, 7500 for $3. Seems they are both in the wrong places.
I don't think we need a winner's list. There isn't really anything to win there. As far as guidelines, my guess is that the same as for non-extra credit items applies here.
However, in order to be "extra credit", and have any incentive, the values really need some work.
A $3 Dunkin card for 12000 points is not attractive at all, esp since there is a $3 card for 7500 points listed as well, no extra credit required. Same is true for the $5 Red Robin card I in another post.
Ah well, I still hope there will be some cool merchandise showing up someday. Something like iPad minis, or Bluetooth sound systems.
It seems to me that AARP Rewards is truly working hard to make their site and rewards worse. It cannot be by chance only, it has to be by design. The descent into irrevelance is rather amusing and I do give AARP Rewards extra credit for that.
