Thank you for delivering the stamps to our mailbox. They’re just what we ordered.
As a customer to your service I thought I’d give you some feedback or advice. Hope you don’t mind.
You are in the mail business. Delivering things to people’s mailboxes is your trade. It is therefore a little puzzling that getting an envelope with stamps in it to our house should take you THREE FULL BUSINESS DAYS! Just as a reference: if I order a t-shirt or other random item from another random online store, I usually have it in my hands by the following day. And their business would be t-shirts or other random items, not MAIL.
Just thought I’d mention it.
