Queen-size white duvet cover with navy piping

I lost my queen-size duvet cover set yesterday around 3pm near the Stop & Shop on Route 7 in New Milford. It's a white 100% cotton duvet cover with slim navy piping and two matching pillowcases in the same style. There's a small coffee stain near the top seam and a faint lavender 'AM' initials embroidered on the inside corner, just under the tag. It was a comforting gift from my grandmother, and it has sentimental value; I really need it back. If anyone found it, please reach out—I’d be forever grateful.
