Discount User Upgrades

[Jake Hakoda Shirley]

Hey guys, we have a tiered upgrades system, and I was looking for a way to discount higher upgrades if you purchase a lower one.

Example:
I buy Gold Donor for 20$, and want to upgrade to Diamond Donor (Normally $30), but since I payed $20 already, it's only a $10 upgrade.

I haven't figured out a good way to do this. =/ Any ideas?

You might want to speak to Naatan, as he created this add-on: http://xenforo.com/community/resources/advanced-user-upgrades.639/

Interestingly, he includes some tiered options.

Not sure how it works with your model, but it allows you to disable some user upgrades for users, if they've already bought another.

So I guess it would mean that if someone buys your Diamond Donor upgrade it would automatically disable the Gold and (presumably) Silver upgrades so they couldn't accidentally buy multiples.

I just don't know how it would work in the other way you want.

You can configure upgrades to disable other upgrades. That allows you to setup tiers. Hopefully you don't have too many tiers or it can get a little hairy.

I can come up with something if you can sponsor the project
