Gambling?

[Jin]

So I have a lot of money to spare but can't find any way to use it? In BL2 you could gamble but here there is nothing to do with money?

The only thing you can do with money is use it at vending machines. Or if you manage to get 8 million you can buy a useless tour of the worlds largest bullet for an acheivement.

Alright, thanks. Is the Orange ammo upgrade the last one? I saved for that but it seems to be the last.

I think that's the last one, minus what you probably can upgrade to near the shops out by Crawmermax. Maybe something in the robolution, too, but it didn't have quite the experience for multiplayer death as Crawmermax can provide (doing it single player, or trying to, was always fun anyway... not that I succeeded!)

It gets to a point where the money is ridiculous. You'll likely notice that in BL2 and the pre-sequel, they toned done the amount of cash and item values, and are more likely to be saving money to get something special (or hoping to find something special) than in BL.

Then they added in the torgue tokens and seraph crystals. Not playing much multiplayer, I have never been able to get enough of either to buy anything I'd want to save for.

The bullet tour is worth doing if you want the achievement associated with it, but in the long run you will get that money back if you play normally and through the DLCs.
