Get several stuff packs for Sims 3 for $9.97 and $9.99 EACH via a ONE-TIME only download with Origin. Back it up once downloaded i'd suggest. This is part of a deal-a-day type thing, so unsure if this offer is for one day only or if it lasts for the entire promotion period which ends 11:59pm December 25th.
Please note this is not the Sims 3 game itself, just stuff packs.
Alright deal, you could get physical copies of these expansion packs at EB Games for $9.95 a while back though.
