After emailing Vistaprint, I received an email letting me know how sincerely sorry they were for the issue and that they would expedite a replacement order free of charge!!!
Our save-the-date’s arrived today safe & sound!! And I couldn’t be more happy with them! We started handed them out to those we saw today and the rest will be mailed out on Monday. Once I have shared them with our guest, I’ll make sure to upload a photo so you can all see them.
