I have a similar problem. I can't belive EA didn't add a button to empty your cart other than one item at a time! I am not going to go through 75 items one a time. Talk about ridiculas. If the Sims 3 store can't be resonable then I will just stop using it as there are plenty of other places to get stuff from and anyway much of the stuff in the Sims store eventually finds its way into future stuff and expansion packs.
i just posted that as a suggestion in the ideas forum if you would like to say yay or nay feel free
i just had the same issue as op; hit "add all" while looking at the custom content for a mansion, ended up with 110 items in my cart. Found this thread with the same complaint.
Then I saw the date...* 7.5 years ago. lmao, i guess they didn't really like that suggestion, huh?
@dirty00Jersey Sims 3 was almost out of development when this thread was posted, and there was very little work done on the store site after that, other than some basic maintenance. So it's not surprising that nothing changed.
Since this is so old though, and the problem isn't likely to ever be addressed, I'll lock the thread.
