From Middle English shoppe, schoppe, from Old English sċoppa (“shed; booth; stall; shop”), from Proto-Germanic skupp-, skup- (“barn, shed”), from Proto-Indo-European skub-, skup- (“to bend, bow, curve, vault”). Cognate with Dutch schop (“spade, kick”), German Schuppen (“shed”), German Schober (“barn”), French échoppe (“booth, shop”) (< Germanic). The verb is denominal. The noun senses “act of shopping”, “purchased items” are backformed from the verb.
Commonly used with 'at' or 'in' to describe location; in American English, 'store' is often preferred for retail contexts.
