I got it, but just barely. I needed to buy more simpoints, but for the last week or so the "My Account" page has been broken. Thankfully, I was able to buy simpoints through the EA store (a helpful hint, if this ever happens to anyone else!) but they took almost an hour to show up on my account on The Sims 3.
Anyway, I'm just grateful that I was able to get the version without Buccaneer's Bounty since I already had that set!
