I do have all the interestes&hobbies checked on my profile to ensure that I receive all offers. The surprising thing, is that after contacting MyPoints customer svc, requesting the link for the offer, they didn't send it to me, rather just telling my to fill out all the item in the profile. (Which already were checked)
I guess my points is, unless you have the link to use, this isn't available to everyone, hence not much of a tip...
