Only businesses I can think of that have a legitimate reason to be cash only are businesses related to cannabis.

I don’t really know enough about your particular business to say anything useful but I will drop something about the 50% sale and you not making sales.

Depending on your business and demographic sometimes costing more will boost sales. People either look for deals or they look for quality. Since they don’t typically know good from bad quality they base quality off of price. Back when I did sales we would sell above our competition and just say something along the lines of “you get what you pay for” and it would work. People would assume you were better because you cost more and they’d be happy thinking they have the best product in the market. It all depends on your demographic though.

All nicotine products are now considered tobacco products even if they have no tobacco. You’ll need a tobacco license.

Their mark up is not sustainable, either they’re selling for a loss to get customers in so they can jack the prices up later, they’re also a distributor, or you’re getting a shit deal from whatever distributor/s you’re using.

Can you give an example of a disposable and their price on it?
