Not that I'm aware of. It will cost around $120 to get 48 decks. If you only use one color Tally-Ho, you can get 48 decks at Theory 11 and have 52 forcing decks.
If you like different colors, check out Kardwell's Tally Ho Pinochle Decks (each deck has 2 of the 9,10,J,Q,K,A for each suite):
https://www.kardwell.com/page/KII/CTGY/TALLY-HO-CIRCLEBACK-PIN-RI. If you get 4 boxes at $30 each, you will have 24 red forcing decks and 24 blue forcing decks.
You can cut your price in half if you do a 50/50 force deck.
You could probably sell the extras for $10 each, getting a 300% return on your investment (assuming you sell all of them).
