Several gun-related businesses were suddenly — and without warning — disrupted in recent weeks when Intuit stopped processing credit card payments because sales were gun-related, The Post has learned.

Some of the payments stopped didn’t even involve firearms, but simply T-shirts and coffee mugs and gun safety classes, according to small business owners.

As a result, the businesses had to scramble to track down customers to get them pay their bills after Intuit credited back to customers’ accounts the purchases — even if the T-shirt was already shipped or the class already taken, one businessman told The Post.
