If you're still unable to get Town Life or you have no way of registering the base game like me, go through the origin store and search Town Life. The price should say $0 dollars now.

I went through origin on my desktop and found it that way anyway, but here's the link to it in the store:
Get it while you can! It ends on Valentines' Day (Feb 14th)!
As for me, I have it finally!!!
Thanks EA! Nice you gave up something for free!
Also thanks Caspin for helping me and Crinrict for posting that bit of info! Thank you! You guys rock! :D
