Make me an offer?

It looks like I don't have an opened Mario Bros or Urban Champion so I retracted one each of those, but I did dig up a bit more. That Animal Crossing Series 2 package may not look like it, but it's empty (took it out through a slit in the top; replaced foil pack). Everything else is unopened.
That's Animal Crossing 067 but I don't have another. Still, I'm missing most of the AC set, so if you can make it worth my while, what's one more? Still, I'm more hesitant to let it go than others. The envelope is an eReader/SMA4:SMB3 Nintendo Power promotional offer sent to my address. It is unopened. The offer was for a subscription, game, cards, guide, and coupons for money off a GBA SP and eReader. I think there was also mention of a link cable but I can't recall if that was included or if it was another discount coupon.
I'm looking for any Animal Crossing cards and Clu Clu Land.
