I just opened my game today and found the trolley mentioned. I have all the packs. I clicked on the trolley to see what was being complained about and it told me that I had everything but did NOT send me to a shop to buy Tshirts or anything else.
It was about buying new or packs you don't have yet. It might even let you know of cheap sales you were looking out for.
I don't see much wrong with it myself. I start my game directly from a Sims4 icon on my Taskbar and don't go through the EA games portal at all now.
