There was a delay in receiving the envelopes from Express, but once I phoned and spoke to the lovely lady, she helped me out. In fact, the carrier had delivered them to the wrong address but the lady at express sorted it all out for me. Thank you Marie!
Very good quality self-seal product - delivered before 10.30 am the next day. excellent service, Thanks, David
I had a last minute invitation to send out. Express Envelopes had the right envelope for the job and they arrived next day. Perfect.
