If you received a refund check from Wal-Mart, the retail giant confirmed it is indeed real and not a scam.

Police in Wisconsin warned people about a scam after some people received these letters, WISN reported.

However, it turned out this was no scam. Wal-Mart sent the record straight that the checks could be cashed safely.

The refund stems from an overpayment at the pharmacies, vision centers or care clinics.
