The nationwide promotion, offered for the first time this year, applies to public-school and private-school teachers, the Arkansas-based chain announced Monday.

Teachers who register their receipts at www.walmart.com/teachers will get Walmart eGift cards worth 10 percent of their purchases of school supplies.

Steve Bratspies, executive vice president of general merchandise for Walmart’s U.S. division, said in a statement that teachers spend an average of $1,000 each year readying their classrooms, “and half of that comes from reaching into their own wallets to make sure students have what they need.”
