Hey ladies, I don't normally do this, but I just wanted to share a great experience. I ordered my invitations from Party Girl Invites and I am so happy with them! They are located in Barrie, Ontario - so great for Canadian brides, but they ship anywhere. I believe they are a new business so they are still on top of things and try really hard to provide great customer service lol. The invitations were cheap - I think I only paid $2.75 each or something and the best part is that they give 10% of your order to charity. They have their own that they support or you can choose one - I gave mine to Humane Society. Anyway, I just thought it was a cool thing to do, so I thought I'd share! I don't think they have a website yet, but here is their facebook page. Cheers!
(The only thing is that their invitations are quite modern, so if you're looking for the ultra traditional, you probably won't like them)
