Some positive experiences I'v had using clickrewards.com:
Have used clickrewards.com site to purchase items, in order to increase my AA Account.
Can redeem blaocks of 500 clickrewards.com points for AA Frequent Flyer Miles.
It usually takes several weeks for miles to post on your AA Frequent Flyer account.
Most stores via clickrewards.com offer 1 point for each dollar that you spend, but some offer 2 or 3 per puchase.
A negative experience using clickrewards.com:
I've had a few orders which never posted points to their site and they NEVER answer any e-mails or auto-messages thru their site.
Somewhat frustrating, as a consumer!
Then again..it's a website and not an actual store.
Hope this info is beneficial to all.
