In Memory of Our Volunteers
"We pause to honor and remember the treasured members of our crew who have passed on. Their dedication and spirit remain part of our journey always."
"The people running the store are super sweet and genuine, and the prices are very reasonable. They are CASH ONLY and there is a second entrance around the side along the street with a separate check out for home goods and craft supplies."
"I love the store they always have new or slightly used clothes at an affordable price. I actually do not shop anywhere else. I'm on a fixed income and you would never know it by the clothes I wear from Mary Martha's all name brands..."
"Cute store with lots to choose from. Something different every time I go in there. You never know what you're going to find 🥰... They have men's women's children's clothing on one side and then the other side they have knick knacks utensils, kitchen things, books... Very reasonably priced"
