Facebook + Twitter + Google Plus Modules - MarketInSG

Hi

Found two combo Google Plus, Facebook, and Twitter modules:

Facebook + Twitter + Google Plus Modules Package

Facebook + Twitter + Google Plus Modules Package (SLIM)
http://www.opencart.com/index.php?route ... nSG&page=3

1. How is the SLIM version different from the other version?

2. The descrips in both say "A package for Facebook, Twitter, and Google Plus." However, in both listings, the Twitter + Facebook is listed as a separate module from the Google Plus. Do you have to purchase two different modules to get all three, Google, FB, and Twitter?

Thanks
