Marcus Munitions has expanded its business with storage deck upgrades (SDU) in Borderlands 3. In previous games, these could be purchased at Crazy Earl’s Black Market. Earl only accepts Eridium for his services. Marcus, on the other hand, accepts regular cash money. And you know it, “No Refunds!”
What are storage deck upgrades?
With storage deck upgrades you can expand your inventory space. There are a variety of upgrades you can pick up. You can purchase the same type of storage deck upgrade a couple of times. You got upgrades for your different types of ammo, your grenades, backpack space, bank space, and the ‘Lost and Found’ machine.

How much inventory space do I have?
One of the big questions for Borderlands 3 is how much stuff can you carry with you. Well, I can tell you that you will start off the game with more backpack space and you will end with more space than in previous games.
- Pre-Patch Storage Space
- Max Backpack Size = 40
- Max Bank Space = 50
- Max lost and found storage = 13
Patch 4 Update – Nov 21, 2019
All characters now begin the game with 20 bank slots instead of 10. The existing Bank SDUs will give everyone a total of 100 available spaces. An additional 10 Bank SDUs are available to purchase in Marcus’s shop on Sanctuary III using the in-game cash currency, each awarding 20 spaces, for a grand total of 300 total bank spaces!
