Come by

A loyal friend is hard to come by.

They burned the old gun that used to stand in the dark corner up in the garret, close to the stuffed fox that always grinned so fiercely. Perhaps the reason why he seemed in such a ghastly rage was that he did not come by his death fairly. Otherwise his pelt would not have been so perfect. And why else was he put away up there out of sight?—and so magnificent a brush as he had too.

For example, during the early days of construction, some landowners and local residents felt they were not being kept up to date with what was happening on a day-to-day basis, or that information wasn't always easy to come by.

Your beau came by while you were shopping.
