What is MediaMaster?
MediaMaster is a digital advertising solution designed for convenience stores that use the ShopMate EPoS system. It adds a customer-facing screen at the till which displays brand adverts, wholesaler promotions, and if you wish your own adverts.
In short, while your customer checks out, they’re shown promotions so you capture eyeballs at the point of sale, when customers are paying and often making last-minute decisions.
How Does It Work?
The MediaMaster screen connects to each till in your store and receives a regular feed of up-to-date promotions (wholesaler deals, brand adverts and custom content) automatically.
- Installation is free (if you already use ShopMate). It usually takes under an hour, and you only need to restart the till once at the end.
- There’s no need for you to create your own adverts as MediaMaster provides them. But if you prefer, you can supply your own images/ads and the ShopMate design team can produce the adverts for you.
- The cost? Just £2 per week per store (regardless of how many screens you use). Hardware is provided free.
Why MediaMaster Can Be a Smart Move for Retailers
Fully Managed & Low Effort
You don’t need to design adverts, manage promotions, or update content yourself, MediaMaster does it for you every trading period. That’s a big plus if you’re busy running day-to-day operations.
Captures Customer Attention
Because the screen sits right at the till, customers see it while paying which means promotions get maximum visibility at exactly the moment when customers are likely to make a spontaneous purchase.
Boosts Sales of Promoted Items
Stores with MediaMaster screens typically see up to a 9% uplift in sales of items advertised on the screens while on price promotion.
Opportunity to Earn Extra Revenue
If you like, you can offer ad space on your screens to other local businesses (e.g. a nearby café, a hairdresser, a local tradesperson). MediaMaster uploads the adverts and you keep 100% of the ad-revenue, with no commission.
Flexible & Customisable
MediaMaster isn’t “one size fits all.” If certain wholesaler promotions don’t suit your store, you can veto them. If you prefer to showcase custom adverts (your own specials, community notices, local business ads) that’s supported too.
Is MediaMaster Right for Me?
MediaMaster is a particularly good fit if:
- You run a small or independent convenience store and want to boost sales without a big marketing budget.
- You want low-cost, low-effort advertising at checkout.
- You’re open to additional revenue streams (selling ad space to local businesses).
- You want flexibility e.g. custom or community-based adverts rather than just wholesaler/brand promotions.
With a modest cost of £2 per week and no hardware charges, MediaMaster offers a low-risk way for smaller shops to trial digital screen advertising as a considered investment.
How to Get Started
- Contact ShopMate to request MediaMaster.
- Plan your adverts: select which automatic wholesaler/brand promotions to add, and decide on your own adverts, or local-community ads.
- Think about how many tills/screens you’ll use but remember cost doesn’t increase per screen, it’s per store.
MediaMaster takes one of the most under-utilised moments in retail the checkout and turns it into a subtle, powerful advertisement and marketing opportunity. For a small weekly fee and no hardware cost, retailers get a fully managed digital advertising platform that can boost sales, drive impulse buys and even create new revenue streams through ad-space sales.
If you run a convenience store or small retail shop and want to maximise the value of every transaction without adding workload MediaMaster is worth considering. Find out more here.
