Is there a way to change apps you set as default.

I was wondering if there was a way to change default apps back to asking you which one you want to open. I wanted to go to the play store on my phone for most things. So I set when I click on play links that it would take me to the app. I wanted to look at the nexus 7 on the website though and it keeps taking me to the app. Is there a way to change this.
