Shiver Single vs Maxi Single

I've been looking to get a CD copy of Shiver for a while, and there are two UK versions on Discogs I've been looking at. The first is a digipack single, and the second is a digipack maxi single. They appear the same, with the same product number and track list. The one that claims to be a maxi single is a lot more expensive though. I assume they're the same release, but if anyone knows I'd appreciate some clarification.
