I highly recommend the giveaway ticket. It's a little pricey bit definitely good for that dopamine rush of having a chance at winning. I like the giveaway ticket best when my discount is applied at checkout because then it's much easier on the pocketbook. Makes it practically a steal!
At $100, it seems like a lot, but it's designed for you to use a coupon code to make it free (through EXP, Dragon's Wings, etc.) Gets you 1 ticket in the monthly giveaway.
