8,000 electronic shelf labels. Fourteen days. No closed aisles. That’s the short version of our rollout at Chestnut Supermarket on Myrtle Avenue in Brooklyn — one of the largest single-store ESL deployments we’ve done, and now a store where a price change is a back-office click instead of a printed tag and a walk down the aisle.

The starting point: a full-line store, 8,000 moving prices

Chestnut is a genuine full-line supermarket — grocery, dairy, frozen, produce, household — and its prices move the way supermarket prices do: weekly circulars, supplier cost changes, markdowns, promotions. At 8,000 labeled facings on paper, tag maintenance had become a standing job that consumed a full staff-day every week, and every delayed batch of tags was a shelf disagreeing with the register.

Two weeks, aisle by aisle

Our crew installed rails and mounts on Chestnut’s existing gondolas, coolers, and cases — no shelving refits — and went live section by section while the store traded normally. Labels were bound to products as each aisle went up, with prices flowing from the store’s existing item file. Fourteen days after the first rail went on, all 8,000 e-paper labels were live and updating from the cloud in seconds.

“We replaced 8,000 paper price tags just in 2 weeks. Our team gets a full day back per week — that’s time they spend on customers, not on labels.”

— Operations Director, Chestnut Supermarket

What changed for the store

• The weekly circular no longer consumes a shift of tag-swapping — it posts storewide in seconds.
• Markdowns happen on time, when the decision is made — not when someone is free to walk the aisle.
• The shelf matches the register by construction — both are fed by the same system, which is exactly what price accuracy inspections test.
• ~A full staff-day per week recovered — roughly 50 staff-days a year redirected from label maintenance to customers.
