Which packs do you regret buying or wish you waited to buy?

Eco Lifestyle. I found out I have ZERO interest in the concept. The only and I do mean only things I use out of the pack are some build/buy items. But it's very few of them. It's just not my cup of tea.

Honestly all of the EPs I should have waited for a price drop, they are all too overpriced imho, but I am just so impatient!
and a couple of the GPs and SPs I should have gotten cheaper too...but other than the price, I do not regret anything, each pack had somethings I enjoy.

Only one I regret is Eco. I like the BB a lot, so maybe I would have gotten it on sale but only guaranteed it wouldn't brake my save like it did. But I didn't enjoy any of its gameplay features.

UNI IT SUCKEDDDDDD

Eco Lifestyle. It was the only pack I've ever bought within a week of release and I'll never do that again. I like many of the features, but the bugs, geez. From now on I'm waiting at least a few weeks until the bugs have been reported. At that point I'll decide whether I want to get it and use CC bug fixes (if any are available), wait for it to be patched, or wait for a sale.

I should've waited for Eco Lifestyle to be on sale because I paid 46 bucks for it instead of 40 due to a tax increase in my country. I only played with it for like a week or two, haven't really been in a Sims mood for a while now since Jungle Adventure so I have barely played with Get Famous, Island Living, University, Strangerville and Magic Realm. I wish I had waited for those to be on sale too. Not that I think the packs are bad, I actually like them, but just have been busy with life.
