Okay, that makes more sense. It wouldn't have occurred to me to scroll past the top search results, down to the Highland Orchards in Wilmington.

And it turns out that they deliver on the same day ... to the same place ... where I pick up my CSA that is not Highlands Orchards.

Between their SEO and their brick-and-mortar marketing, I wouldn't have known about Highland Orchards (DE) -- so thanks for the tip, Reddit ftw again!
