Have! I got one from there before, just that it's from the dealer shop as I was aiming a particular number.
But there are a few MyNews outlets there... 3, IIRC. One of them is one floor down from the Digi dealer shop, near the escalators (nearest telco shops). I went there to check and they'd stock back then - no harm checking.
Edit: According to their directory, Level G Lot 33A, Level 4 Lot 23... Otherwise check with Digi dealer shop Level 3 Lot 50, coz I remember going down instead of up... they're the ones who pointed me to MyNews for RRP SIM packs.
