Our message in the bottle invites were total including stamps: $455
(we bought ink for the color printer for our lables and invites, paper, stamps, shells, twine, $200 were for the bottles, stamps were the second most expensive part)
I used company resources for our table cards, favor tags and luggage tags, so that was almost nothing (shhhh....don't tell :-) )
What type on invites are you looking at buying?
