Pop into your local branch of Morrisons and you can choose from a lovely little selection of fireworks to brighten up Bonfire Night.
But a tweet from the supermarket posted on Thursday morning has got us wondering if there's a secret password that gets you into a fairly terrifying back room.
That's right, the bomb warehouse.
Now we're sure 'Natz' has just had a simple misunderstanding and isn't Guy Fawkes's go-to gal for supplies.
And to be fair, she's not the only one.
Oh dear...
A Morrisons spokeswoman said the tweet had been sent in "human error".
'The last thing we want to do is offend anyone at all," she added.
