Retailers owe moms a big "thank you" this week, too.

Spending on Mother's Day gifts this year is expected to boost the retail industry by nearly $20 billion, according to a survey by the National Retail Federation. That's about $3 billion more than consumers were willing to spend for Valentine's Day gifts.

The average consumer plans to spend about $163 on greeting cards, flowers and other gifts such as jewelry and lifestyle products. The survey found that brunch or dinner outings with families will account for about $3.8 billion of the total holiday spending.

"As one of the most universally celebrated holidays, retailers will take this opportunity to attract Mother's Day shoppers with promotions on ladies apparel items, health and beauty products, jewelry and even restaurant options," said NRF President and CEO Matthew Shay.

More Season, Moons

Southern Season, a gourmet grocery store with locations in Mount Pleasant and Chapel Hill, N.C., is opening a third location in Richmond, Va.

The 50,000-square-foot store will open this summer at Richmond's Libbie Mill, a new pedestrian-friendly mixed-use project in Henrico County.

Palmetto Moon, another retailer based in the Carolinas, is also growing. The lifestyle apparel and gift chain with eight locations across the state is opening a ninth store in Columbia at the Village at Sandhill Shopping Center. Palmetto Moon announced this week that it's also doubling the size of its Myrtle Beach store in Coastal Grand Mall.

Closing

Attic Treasures, an antiques shop that's been in business at 2024 Wappoo Drive in James Island for more than 20 years, is closing at the end of the month. The store is offering 30-50 percent off its remaining inventory until it closes.

Manny's Neighborhood Grille, a locally owned Greek restaurant, has closed its downtown location at 41 George St. near the College of Charleston campus. The eatery still operates at 1680 Old Towne Road in West Ashley and 3032 W. Montague Ave. in North Charleston.

Newcomer

Cedar St. in Summerville from 108 E. 3rd North St. At the new gallery, there will be on-site custom framing by co-owner Marsino Zandri, who operates the business with wife Noelle Zandri. The gallery also features a large collection of oil paintings, local art and handmade jewelry.

For the kids

For each coupon book sold at the shopping center, Tanger puts $1 toward its annual education grants, which are awarded to schools in each market with Tanger Outlet Centers.
