Last I heard that was a no... but I think some of the rewards like House of Blues, Wolfgang Puck, don't count against your 3.
It seems that you need to purchase at least $50 in chips to get the 4th reward; i.e. $39 twice or $39 + $19 or probably $39 + $9 + $5.
actually there is no set dollar amount, no one knows what triggers the 4th reward. Part of it is money spent and part of it is "play style", whatever that means........ My wife bought 2 $39 packages back in February and still has 4 rewards. There's a facebook group that is the only group out there that runs Q&A sessions with the developers. The above is what the official word is.
From recent discussion on FB pages it seems to require $50 spend to get the 4th reward. Multiple people stated (and my own experience is the same) that a single $39 purchase will not grant the 4th reward and nor does $39 + $5. But $39 twice usually does the trick.
