Shoppers at Kmart stores in several states are finding their layaway accounts for Christmas gifts being paid in full by anonymous donors, according to the Associated Press.

Executives with the retail chain said the phenomenon appears to have begun in Michigan and spread to stores in Indiana, Iowa, Montana, and Nebraska, with dozens of customers being notified that their balance for toys and children’s clothes have been fully or nearly covered.

Benefactors generally ask to help families that are deferring payment on items for young children. At an Indianapolis Kmart on Tuesday an anonymous woman reportedly paid layaway orders for as many as 50 people and handed out $50 bills as she left the store.

Kmart representatives said they have done nothing to instigate or spread word of the giving. “It is honestly being driven by people wanting to do a good deed at this time of the year,” said Salima Yala, a vice president with the company’s layaway division.
