If you stuff your own envelopes you’ll appreciate this bit

We’ve got our own mailing line. We can distribute your work straight from the press, keeping things quick and keeping costs down (we’ve got money-saving contracts with Royal Mail). We clean and sort your database and print bespoke address carriers, customized with your name and logo; we then package and prepare for collection and delivery. For most jobs, just hours.

If you’ve ever sat up all night licking envelopes you’ll know that this is a chore to endure only once. Especially when someone’s itching to do it for you.
