The owner of Round Corner Pharmacy has been in discussions that could end his 27-year run in downtown Lawrence.

But Tom Wilcox is not ready to close up shop — or bring in a new owner — anytime soon.

“The business has been healthy and doing OK,” said Wilcox, who has owned the pharmacy and connected Cheese & Salami Shoppe at 801 Mass. since 1982. “There’s a time I will call it quits, but it ain’t today.”

Wilcox said that health problems had limited his time at the business. But Round Corner has endured, he said, with the support of a “dedicated pharmacy staff,” which is key to the store’s future.

“If I were to lose them for some reason or another, that would be different,” Wilcox said, “but for right now, I’m staying with what I’m doing.”

Wilcox declined to identify the party or parties that he had been negotiating with, but he did acknowledge that discussions had been ongoing for about nine months.

“We have not come to terms,” Wilcox said. “Right now it’s all up in the air.”

Wilcox owns the building at 801 Mass., which includes the pharmacy, the Cheese & Salami Shoppe and upstairs offices.

The Cheese & Salami Shoppe, which prepares and serves sandwiches at the back of Round Corner Drug, poses a logistical challenge for Wilcox.

He finds it difficult to manage those operations while filling prescriptions and tending to other duties up front.

“Right now we’re trying to do our best to see what works back there,” Wilcox said. “I’m not in the restaurant business. I’m in the pharmacy business.”
