the.com/retailer

means A business that sells goods directly to consumers, usually in smaller quantities and at higher prices than it paid to acquire them.

from From French 'retaillier' — to cut again, to cut into pieces — built from 'tailler,' to cut (the same root that gives us 'tailor'). A retailer was originally someone who cut a bulk piece of cloth or goods into smaller, sellable bits — so the word has literally meant 'divider of the big thing into expensive little things' since medieval trade.
