Red Dead Redemption Money Glitch!

After hunting grizzly bears near Tall Trees region in Red Dead, I went to sell all of my furs at Manzanita Post. I had these items in my inventory for sale when I went to the shop in this order:

Hummingbird sage

Bighorn meat

Bighorn skin

Boar meat

Boar skin

Deer meat

Deer skin x 2

Fox meat

Fox fur

Grizzly meat x 9

Grizzly claw x 5

Grizzly tooth

Grizzly furs x 9

Grizzly heart x 2

Rabbit meat

And I went down the list selling everything in order, skipping 1 Deer skin. After doing so, then going back to the Deer skin to sell, I had an unlimited amount, allowing me to continue selling it until i pressed the 'B' button in order to go back to the game. I will try this with other items in different orders and see if it still works. More updated guides to come. Very easy "More than a fistful" achievement which is earning $10,000 in single player. Thanks for reading!

(This had been tested twice, and it works exactly the same. Let me know if you have the same luck trying with other items, less items, different orders, etc. Thanks again!)

Or you could play the game right
