Why cant I purchase?

I went to steam store, and I didn't see anywhere to purchase/download.

Apparently, Sandlot Games' titles aren't available in all regions on Steam. You're not the first person who has this problem. Thankfully, there are several casual gaming portals that also sell their games. Far more of them in fact than they put on Steam.

If you want to get the whole Super Granny series, you'll have to go for at least two different portals though. That's because the first game in the series is only available at http://wildtangent.com/ , but while they have Granny in Paradise and Super Granny 3-6 as well, the one title they lack is Super Granny: Winter Wonderland. On the other hand, while http://bigfishgames.com/ has Winter Wonderland, Granny in Paradise and Super Granny 3-6, they're missing the original Super Granny.

TL;DR: You can buy the first Super Granny from http://wildtangent.com/ , Super Granny: Winter Wonderland from http://bigfishgames.com/ and Granny in Paradise as well as Super Granny 3-6 from either site.
