Avent Anti Colic Bottles ??? HELP!

[kriddledum]

I received 2 packs of 4 oz Avent Anti Colic Advanced bottles (they have a honey color to them) and I want to trade them in for 8 oz. I cannot for the life of me find ANYWHERE that sells these so I can trade them!? Any help?

If your in the US, I know Target and Bed Bath and Beyond carry them.
