But these are not to celebrate her birthday, they're Christmas cards.
Mary, the local organiser for the Cards For Good Causes Christmas card charity, takes delivery of her stock tomorrow – which happens to coincide with her birthday.
"How many people can say they get that many cards?" she laughs.
The shop is in a different location this year because it has had to move out of Sheffield Cathedral after 10 years.
Instead, it's moved to the Scout headquarters building in Trippet Lane and Mary is anxious to tell her customers where it is.
She says: "I'm hoping all our dedicated customers who come back year after year will find us.
"It's just 100 yards from the City Hall tram stop."
