More than one Trilegiant Offer?

I already did Complete Home for FreeMiniMacs. Will I get credit for doing Buyers Advantage under FreeiPods? I noticed they are the same company.

Also has anyone tried using a coupon code when signing up for Columbia House. I have some codes for 5 DVD w/ free shipping and you only have to buy 2. I don't know if I will get credit for competing the offer if I use a code though.

Thanks

Yes, you can sign up under more than one of their sites
