I have been waiting and waiting for the sold out $50 FB credit at Monte Carlo to come available. It seems like it never does.
So I thought I would write the support desk at MyVegas and ask if this reward had been discontinued as I wanted to redeem it for a trip to Vegas this month.
Shortly thereafter I received an email with the $50 FB credit to Monte Carlo in my inbox. Sweet!
I double checked and it still says sold out.
So if a reward has been sold out and never seems to come back, just ask!
