Railway Magazine readers
The thing you're looking for is exclusive to Railway Magazine readers, and isn't available to other visitors to our website.
If you read about it in the magazine, you need to go to the web address shown where it says "It's easy, just enter this link"
If you read about it on their website, click their link titled "Click here to get yours!"
If you're using Microsoft Edge / Bing then it sometimes does odd things. For you, try searching in the search box within the blue header of our website – type the web address from the magazine ad in there instead, and it should find the offer.
