WH Smith stores in the UK sell magazine subscriptions like this now. Years ago, they were in a box on a spinner. Now, they are placed with gift cards, taking up less space and better located in-store. That they still offer subscriptions today suggests there is money in it for them. There have been several goes at newsagents selling magazine subscriptions like this in-store in Australia over the years. None has worked I think because it has not been more than one or two titles.
