Single post in Mega Stone Vouchers

I feel that Mega Stone Vouchers have gone up all except the 5th tier one. I honestly feel that the 5th one should be the most expensive, instead of what it is now where it is the cheapest since these are PFQ exclusive megas. Instead maybe make it so during Mass Click Weekend it would rotate through each of the different tier vouchers instead of always being a 5th tier mega voucher.
