Petrol pump advertising is effective in that it gives you 100% share of voice, especially in a media landscape which is full of digital advertising which is usually a 1/6 and space shared with other advertisers.
For our clients, petrol pump advertising is also good way to target rural locations where there are not a lot of poster options available.
We also always find T4Media very professional, cost effective in providing us with deals and offers, and providing proof of posting.
The service you provide is excellent and I would not hesitate in recommending the business to other clients.
