Invitation—vistaprint vs Minted vs ?

It definitely depends on the style you're going for. I like Vistaprint, but the quality is better at Minted. They just look and feel "fancier" - hence the price difference. If you're going for a more casual affair, then go with Vistaprint. If you really don't care that much, then just go the cheaper route. Your invitation DOES set the tone for your event, but it's not a huge deal (at least to me personally) if you go with cheaper invitations. The only time I'd really tell someone to absolutely go with the finest quality invitation would be for a black tie wedding.

FH and I ended up getting invitations from Wedding Paper Divas (now the Shutterfly Wedding Shop), which I think are on par with Minted. We definitely spent a lot more than I generally would've liked (probably around $600 for 110 invitations, detail cards, RSVP cards, and STDs), but they turned out SO beautiful and we've received so many compliments on them. I also plan on framing one of the invitations for my house, so I'm glad I went with something really pretty and high quality. But that's just me.
