St. Patrick’s Day falls on Sunday this year, giving Americans all weekend to celebrate and spend a little more green than last year.

Retailers, bars and restaurants will reap the benefits as spending is expected to reach $4.7 billion, up slightly from $4.6 billion last year, according to the National Retail Federation.

St. Patrick’s Day is the smallest of all the consumer holidays in terms of how much is spent, but it provides a launching pad for spring spending. The average person celebrating the holiday will spend just over $35 on attire, decor, food and drinks.

Eight in 10 Americans will wear a bit of green to avoid the traditional pinch. Nearly 30 percent will attend a party at a bar or restaurant, and 20 percent will attend a private party.

The holiday comes just two weeks before Easter, one of the biggest spending holidays of the spring. Easter is March 31.

The firm

Are you lying down for this?

Mattress Firm plans to build another store less than half a mile from four other mattress stores in West Ashley, three of them Mattress Firms. The proposed store has the same address of an existing Mattress Firm clearance store at the Shoppes of West Ashley, but the planned store is on a vacant outparcel.

The mattress store submitted plans last week to the city of Charleston to erect a new 4,000-square-foot shop at 946 Orleans Road in West Ashley. That’s on an outparcel in front of the Shoppes at West Ashley, where World Market, Party City and Bed, Bath & Beyond are located. Mattress Firm opened a new store in October in the old Party City site on Sam Rittenberg Boulevard, just across from another one in Harrell Square.

The plan must go before the city’s Design Review Board. No date has been announced for the next meeting.

Running in

A new sporting goods shop in Mount Pleasant has announced an opening date. Fleet Feet Sports will open its 100th store in the Whole Foods-anchored Patriots Plaza at U.S. Highway 17 and Houston Northcutt Boulevard on Thursday. It’s owned and operated by Mount Pleasant residents Chris and Amy Minkel and will be the chain’s third store in South Carolina. Look for giveaways and activities as part of the opening festivities March 14-17.

Diving in

A local swimming pool firm that specializes in cleaning and repairs is diving into the retail market. ASP — America’s Swimming Pool Co., which opened in 2006, will open a full-service store Friday at 769 Folly Road on James Island to serve pool owners who take care of their own pools, local ASP owner and operator Wayne Gable said. A grand opening will take place Saturday.

Just for kicks

The gym 9Round Kickboxing recently opened a second location at 1890 Sam Rittenberg Blvd. in West Ashley. Its first gym opened in 2011 at 569 Belle Station Blvd. off Long Point Road in Mount Pleasant.

Participants move to nine workout stations in a 30-minute format without class times that incorporates functional, interval, cardiovascular and circuit-training regimens. The owner is Daniel Woodrum.

On the way

A new Subway is set to open in a former Kentucky Fried Chicken at 335 Folly Road on James Island. The restaurant moved from the nearby James Island Shopping Center and is awaiting city permit approval before it can open.

Also, a new restaurant called Falyn’s on Forty-one on S.C. Highway 41 in Mount Pleasant is in the works. It’s Facebook page says it’s opening soon, but there is no word on the date and no one from the business responded to emails and phone calls last week.
