Oh wow that's a lot of hats!
I might be able to skim a little bit off, but to tell you the truth you'd probably be saving a lot of money purely on shipping. If it was 5 hats like these I could probably fit them all into a single bubble mailer and it'd end up staying around $10 for shipping. :]
That's really amazing of you though, thank you so much for your interest in helping!
Pass me a note as soon as your ready with details, like your colour choices and whatnot, and we'll hash things out! :]
