The tents by the Wilton High School tennis courts have gone up — a sure sign that Minks to Sinks, the largest tag sale in Connecticut, is about to open.

After almost 75 years, Minks to Sinks has become an institution, not just for those who live in Wilton, but for people who come from as far away as Massachusetts to shop for deals on everything from kitchen and household items, to gardening and sports equipment, furniture, kids’ toys, electronics, lamps, artwork, seasonal clothing and more, including minks and sinks.

Antique dealers also frequent the sale, searching for desirable collectible items.

Minks to Sinks is a tradition as well, not just for the hundreds of loyal shoppers who return season after season, but for the volunteers — more than 175 strong — who work tirelessly to make it a success. Many of the volunteers have been giving their time for years, helping out wherever needed, from sorting, ticketing and displaying merchandise to folding up tables after the sale is over. Now their children are volunteers, and often, several generations of families work side by side. The sale raises money to benefit Family & Children’s Agency, the Norwalk-based nonprofit agency that provides much- needed social services to individuals and families in need in the surrounding communities.

The Minks to Sinks spring sale opens at 9 on Saturday morning, May 4. Bargain days are Sunday, May 5, from noon to 4, and Monday, May 6, from 9 to noon.
