Ohhhhh, OK. I didn't read all the details of the email, since I already have PP11.
Since SM owns Content Paradise, have you tried looking there for those items? Not sure that's where you would find them, but you never know.
OK, I just checked, and found Paulne Summer Outfit for that price, and it lists Smith Micro as the artist. Searches for bathroom and kitchen resulted in nothing, so maybe not all is at CP.
OK, did another search, this time on all Smith Micro items, and I think that's where you might find items included in that pack, such as Paul Teen and Pauline Teen. It's possible the kitchen and bathroom just aren't up in any store yet.
