*Update* – Thanks DUTCHEE!
The Fanta Fridge & T-Shirt , as well as the Lord Sponge Collection Stuff, have also been removed from the store.
Back in November, the Sims team joined the World AIDS cause to create special Patterns on the exchange, and a free World Aids poster. As of February (according to Simy.TV) these items have been removed.
I have checked my purchase history and the poster still shows up for download, but it would be best for everyone who managed to snag it, to back up a copy. If there is one thing we can never be sure of, is whether or not the items will be completely removed from the site.
