She made it halfway through the store.

Picture this. A shopper finds a mobility cart, fills the basket with her list half-finished, and then the motor slows. The charge indicator that read full at the entrance is now blinking. She is as far from the front of the store as she can be. What happens next is not a minor inconvenience. It is the whole trip coming apart. She has to flag someone down, transfer her groceries basket to basket into a second cart she hopes is charged, and start again. Or she leaves.

"There's been days where I've gotten halfway through the store, and all of a sudden, the charger goes down. I'm lucky if I get the cart back up to the front and then I have to move my items from the basket to another basket and take another cart."

Research respondent, on battery failure mid-trip

That shopper is not an edge case. She belongs to a large, loyal, growing customer segment that most retailers cannot see, because the moments that define her experience happen in the aisles, out of view of any dashboard.

This paper is about that blind spot: who these shoppers are, what actually happens to them in your stores, and why the mobility cart has quietly become one of the most neglected assets on your floor.

Why this matters to retailers

Two forces are converging on your retail floor. The first is demographic. The 65-and-over population grew 38.6% between 2010 and 2020, its fastest rate since the 1880s and roughly five times the growth of the total U.S. population. That group is projected to reach 82 million by 2050, climbing from 17% to 23% of the country. Mobility limitation tracks closely with age: about two in five adults 65 and older report a disability, and mobility is the most common type. The shoppers who depend on a working cart are a widening share of your floor traffic.

The second force is competitive, though not in the way most operators assume.

Older shoppers are the most store-loyal segment you have. They are the least likely age group to buy groceries online, and when they do order online they favor curbside over delivery. They are less likely to abandon your aisles for an app.

They will, however, drive past you to a competitor. When shoppers change their preferred grocery destination, roughly 60% move to a different physical store rather than shifting online. Our interviews bear this out. Forty percent of respondents told us they shop at two or more stores, and several named the specific store they now avoid because of mobility cart problems. A cart failure rarely pushes a shopper out of the category. It pushes her across the street.
