Who Is the Client?

A supermarket chain headquartered in Lyon, France, operating 120 stores across southeastern France and the French‑speaking region of Switzerland. Positioned as a “community‑focused premium supermarket”, the group prioritises fresh produce, organic food and local specialities. Each store features fresh‑food sections, dry‑goods aisles, checkout counters and customer lounge areas, generating substantial demand for in‑store promotional displays and directional signage in daily operations.

Challenges Faced by the Client

Promotional displays in supermarket stores directly influence sales conversion. The group’s previous promotional display approach suffered from the following problems:

Inconsistent information formats: Some stores used A‑frame signs, some hung posters, and others wrote information manually on blackboards. This created visual clutter for shoppers, who struggled to identify key promotions.
Time‑consuming and labour‑intensive updates: Every Wednesday was the promotion change‑over day. Staff had to replace hundreds of posters and price tags throughout each store, leading to frequent errors and high labour costs.
Vulnerability to damage and dirt: Paper posters curled from moisture in fresh‑food zones and collected dust in dry‑goods areas. Frequent replacements resulted in exorbitant printing costs.
Lack of magnetic functionality: Staff wished to display supplier‑provided sample photos, test reports and other materials alongside promotional content to build customer trust, yet conventional display boards could not hold such items magnetically.
Difficult chain‑wide standardisation: Promotional display practices varied widely across the 120 locations, preventing the group’s marketing headquarters from maintaining a consistent brand identity.

Solutions Provided by Vwin

After receiving the client’s enquiry, Vwin thoroughly analysed the supermarket’s promotional display scenarios and promotion‑change workflows, and recommended a tailored portfolio of display whiteboards:

Client Pain Points	Vwin Display Whiteboard Solutions
Inconsistent display formats	Uniform dimensions and styles. All 120 stores are equipped with display whiteboards of identical specifications for consistent brand visuals.
Time‑consuming updates for promotion switches	Dual‑function boards supporting dry‑erase writing and magnetic attachment. Promotional content can be hand‑written or updated via magnet‑mounted inserts. Change‑over time is reduced from 4 hours to 40 minutes.
Easily damaged, soiled and unhygienic displays	Matte baked‑enamel surface with an aluminium alloy frame, waterproof and stain‑resistant. Surfaces can be effortlessly cleaned with a damp cloth for extended service life, eliminating frequent paper poster replacements.
Need to showcase sample images	High‑quality galvanised steel backboard with strong magnetic force. Supplier sample photos, test reports and origin certificates can be magnetically affixed directly onto the board.
Standardised chain‑wide management	Each display whiteboard is custom‑printed with the group logo and store number. Headquarters designs unified layout templates, providing clear benchmarks for store audits.

In terms of product specifications, Vwin offered two sizes adapted to different store zones:

Main Promotional Board for Fresh‑food Sections: 120×180 cm, wall‑mounted (floor‑stand version optional). Used to feature weekly special offers, direct‑from‑farm sourcing information and new‑product recommendations.
Checkout Impulse‑buy Display Board: 60×90 cm, countertop‑placed or wall‑mounted. Designed for add‑on offers, loyalty‑point redemption announcements and limited‑time discounts to drive impulse purchases.

All display whiteboards feature premium galvanised steel back panels with matte baked‑enamel surfaces, delivering smooth writing performance, residue‑free dry erasure and long‑lasting magnetic strength. The aluminium‑alloy frames are minimalist and durable, matching modern supermarket interior designs. Each board is divided into a fixed‑information zone (non‑erasable printed logo and static fields at the top) and a flexible update zone (writable and magnet‑compatible for daily content adjustments).

Supporting accessories are supplied as a complete package: 30 magnetic fasteners per board, 20 A4 flexible magnetic sheets (pre‑printed with weekly date columns), a four‑colour whiteboard‑marker set and a specialised eraser. During promotion change‑overs, store staff only need to update text on the flexible magnetic sheets without rewriting the whole board surface.

Delivery and Services

Following sample confirmation, Vwin completed mass production within 25 working days.

Total quantity: 240 display whiteboards (2 units per store × 120 stores: one main fresh‑food promotional board plus one checkout impulse‑buy board for each location).

The top of every whiteboard is pre‑printed with the group logo, store number and weekly date field to guarantee uniform brand presentation.

Fixed information fields (product name, country of origin, unit price, member price, promotion validity period, etc.) are printed at the board bottom. Store personnel only fill in specific values instead of redrawing tables repeatedly.

Goods are shipped by sea to Le Havre, France on CIF terms. Vwin takes full responsibility for insurance and transportation.

Supplementary deliverables include installation manuals, promotion‑change‑over operation guides (featuring weekly‑update SOP flowcharts) and routine cleaning‑and‑maintenance instructions.

Results

All 240 display whiteboards were distributed, installed and put into operation across the 120 stores within 5 weeks.‑ Key metrics from the group’s marketing‑execution audit conducted 6 months later:

Promotional‑information accuracy rose from 71 % to 97 %.
Average store promotion‑change‑over time dropped from 4.5 hours to 40 minutes, cutting labour costs by approximately 85 %.
Annual procurement costs for paper posters decreased by roughly 70 %.
Conversion rate for promoted merchandise increased year‑on‑year by around 15 %.
The customer‑satisfaction survey score for “clear and legible promotional information” improved from 3.2 to 4.6 out of 5 across stores.

The group has added these display whiteboards to the mandatory procurement list for all new‑opening stores and intends to expand its product portfolio to mobile‑stand whiteboards and cork notice boards, with continued supply from Vwin.
