You must have gone through a lot of peacock wedding invitations. I saw some on Zazzle recently and was pretty impressed with the collection. It can be a bit tiring going through the entire collection of peacock invitations on Zazzle. My Squidoo site - Best Peacock Wedding Invitations - tries to bring you the best of the lot.
The good thing about Zazzle is they offer invitations for a great price in bulk. You will absolutely love some of the cards there!
