USI Mercato 3000 26 Selection Snack Vending Machine – WS3000 Black Diamond

USI Mercato 3000 Snack Machine — 26 Selection Glass-Front Merchandiser (WS3000 / Black Diamond)

The USI Mercato 3000 snack machine is a full-height, small-footprint glass-front snack merchandiser built by U-Select-It on The Wittern Group’s Mercato platform. This unit is the 26-selection configuration, sold over the years under several catalog names — 26 Select Black Diamond Snack, WS3000 HR Series, SV3000, and AB23 — all describing the same 3-wide cabinet. At 72 inches high and just 29.3 inches wide, it delivers real snack variety in spaces where a 39-inch-plus machine simply will not fit, which is exactly why operators favor it for offices, break rooms, waiting areas, and smaller commercial sites.

Behind the tempered-glass front, coil trays present chips, candy bars, cookies, pastries, and other packaged snacks. The Mercato 3000 platform holds up to 360 items in its maximum layout (114 snack, 198 candy, and 48 pastry positions per the factory sheet), with actual counts depending on how the 26 selections are configured. Vending is protected by USI’s iVend guaranteed-delivery sensor: an infrared beam confirms the product actually dropped, and if it did not, the customer gets the selection re-vended or their money back — a proven way to cut refund complaints at unattended locations.

Specifications

Key Features

• iVend® guaranteed delivery — infrared sensors verify every vend; no more “it got stuck” refund calls.
• Full MDB payment bus — runs a standard coin mech and bill validator, and accepts any MDB cashless device, so a Nayax or similar credit-card reader installs without rewiring.
• Flex Shelf technology and motor pairing — trays adjust to product height and adjacent motors can pair to vend wider items.
• DEX/UCS data port — pull sales and inventory data on route visits instead of counting by hand.
• LED-lit glass front — full product visibility with lower energy draw than fluorescent lighting.
• ADA-compliant controls with Braille keypad — placement-ready for schools, government, and corporate sites that require accessibility compliance.

About U-Select-It (USI) and The Wittern Group

USI is the vending brand of The Wittern Group, a family-owned manufacturer headquartered in Des Moines, Iowa, that has been building vending equipment since 1931 — one of the oldest and largest vending machine makers in the United States. Wittern machines (sold under USI, Fawn, and related names) are known for straightforward electro-mechanical designs, broad parts availability, and long service lives, which keeps refurbished and later-life units like the Mercato series economical to run and easy to repair.

Where the Mercato 3000 Earns Its Keep

The Mercato 3000’s narrow 29.3-inch cabinet is the whole story: it fits through standard interior doorways and into corners a 4- or 5-wide machine cannot. It is typically placed in offices of roughly 30–100 people, employee break rooms, auto shops and waiting rooms, salons, laundromats, small gyms, apartment amenity areas, and school or clinic corridors. Paired beside a can or bottle drink machine, it completes a compact snack-and-drink station.

Operators typically service a location this size on a weekly or biweekly route; the DEX port and iVend sensor keep shrink and refund disputes low, and adding an MDB card reader typically lifts sales at cash-light locations. Sizing rule of thumb: match the 26 selections to your best sellers rather than maximum variety — full coils sell better than wide, half-empty ones.

Does it take credit cards?

The machine uses the industry-standard MDB payment bus, so any MDB cashless reader (such as a Nayax device) plugs in alongside the coin changer and $1–$20 bill validator. Tell us at order time and we can configure it card-ready.
