There are cheats out there that unlock different sponsorships, along with their items. However, sponsorships, when unlocked normally, are unlocked in a random order. Some people's fifth sponsorship could be Nike, while someone else's could be EA Sports. The order in which they are unlocked are randomized, but the price for each sponsorship per item in Season mode is already determined on the level on the list. So, if EA was your fifth sponsorship, you would get $500 per item used in Season mode. But, if you unlocked it later on, say if it were your tenth sponsorship, you could get $800 per item. So, if you are looking to use a password to unlock a certain sponsorship and their items, use other passwords first. That way, when you do unlock the sponsorship you want, you will get more money per item in Season mode.
