So the PHSC fall fair https://phsc.ca/camera/fall-fair-oct-20-2024/ is tomorrow ... for those that have recently gone to their fairs ... are the sellers Cash only, or they now adays have interact?
When there are shows like that around here, there are frequently signs near the door telling people where the nearest ATMs are .
Sometimes individual vendors will accept eTransfers, but I would be cautious with that.
When I last shared a vendor's table at one of those, I brought money to make change, and made pricing decisions with ease of making change in mind.
