The problem · the silent bounce
Your customer is two miles from a yes.
They’re on the product page, ready to buy, and they’d happily pick it up today — if they knew which of your shops had it. Most storefronts can’t tell them, so they go and ask the question somewhere else. Often that somewhere else is a competitor who can.
A separate “find a store” page doesn’t fix it: it makes them leave the product to go hunting, and it still doesn’t say whether the item is actually on the shelf. The answer has to be on the page, and it has to be live.
