Discounted $BLOOD purchases for Holders

I am proposing some sort of discount for blood purchases/auctions.

The following percentages are just examples, but outline the structure in which I am proposing.

• 50% discount for holding Vamps
• 5% discount for holding Bats
• 5% discount for holding Vampiress
• 5% discount for holding a Perfect Pair

Pros:

• Brings value to across the collection

Cons:

• Could negatively affect BLOOD prices
