That, and it seems like there's better offers in the starter packs. And sometimes, even older items that haven't been offered since release date have been offered in the starters.
I'm not sure if it's to convince a newer player to buy one, or something - but I seen a while ago that a starter pack was offering the Lollipop center. And was a bit jealous that I couldn't get it on the actual bakery I wanted it on.
I didn't know about the starter pack being offered for lower level players.
I thought or was speculating that is was because they hadn't spent money into the game.
I bought a started pack on Restaurant Story some time ago, and now I don't get them anymore on that specific account. So now I only get the value packs.
So even if you get them starter packs, you buy one - and they're gone.
