8 Suits, as you guessed is a deck of playing cards with an additional 4 suits, the clover, tear, crescent and star for a total of 104 cards plus a number of jokers.
Priced at $12 USD per deck plus $5 per postage ($13 per postage internationally), it is a little steeper than The Fat Pack, at roughly $16 USD including international postage. Unfortunately, I discovered the former after ordering the 8 Suits.
