He said they were having a problem with their inventory control system, so they didn't really know what they had on the shelves. They were sticking with their ads from, I guess, three weeks ago," stated Craig Walsh, a customer. Not only have the ads been down at all three grocery stores, but customers also reported issues with payment systems. Happy Mart set to open at Market City Shopping Center "I come here a lot, and I noticed recently that debit cards just haven't been working at the self-checkout. I usually have to pay cash after my card isn't accepted," said Maxwell Wiemken, a customer. Those needing to pick up prescriptions from the pharmacy had to send their medication elsewhere, according to customers.
