We are on a tight budget and we are cutting costs at every corner. I am preparing my wedding invites and strongly want to include our website URL at the bottom of our invites so we don't have to pay extra for inserts. The internet tells me that this is an absolute no, but I really don't understand the need for an entire insert just for a URL. The whole point is to save money on our invites and postage. I don't think it looks tacky at all. I simply included at the bottom of the invite "Kindly RSVP at" and then the URL. We also had the URL on our Save the Dates. The internet confuses me. Thoughts?
