Bundled subscriptions seem to be a trending topic of discussion lately, even though there are not that many domestic publications using them. But Finnish paper Helsingen Sanomat‘s long-standing bundled offer can provide some interesting insights.In 2006, Helsingen Sanomat decided to offer a “Combo” subscription package that bundled access to both print and digital versions of the paper, according to Poynter’s Rick Edmonds. They’ve seen some success with this strategy, with bundled subscriptions accounting for a third, or 120,000, of their 360,000 subscriptions. This allows them to keep readers loyal to their brand across multiple platforms – print, digital and mobile (which is increasingly important as mobile users are expected to near 6 billion this year – just 1 billion short of the total world population).However, they’re clearly not maximizing their bundled offer with their pricing strategy. The 1 euro charge per article is a nice feature for visitors that avoids a leaky paywall, but it would be better if they presented their 30-day, 90-day, 180-day and 365-day billing periods and monthly, quarterly, semi-annual and annual rates.Why force people to make another purchase decision a month or year later?
