Found this link....
If you don't already have a Club Carlson number you might be able to get 4500 from opening using this link. Then after you open you can request transfer of the 500 free through Erewards..

I found this on the frequentflyerbonuses.com page and it stated it MIGHT be targeted. Since my husband did not have an account I set it up then did the Erewards 500 free offer. Crossing my fingers I could have 5000 free in a few months! Which I will transfer to miles...
