Support

It's done automatically. When you try to buy a Deluxe subscription it will give you an auto discount based on your existing subscriptions and how long you've been a subscriber. It's one of the new features in Akeeba Subscriptions Professional called "flexible discount". I am always "dogfooding", i.e. I use the new features on my own site before anyone else does on his/her site :)

As you can already see on our site, they are not presented in any way on screen. The actual discount is calculated on the subscription page. This is by design. If you give it a coupon and it has calculated an automatic discount it will always pick the biggest of the two, not combine both. It can't know if you intend to use a coupon code beforehand.

No. AS doesn't care if it's a new subscription, a renewal or an upgrade. All it knows is that user X subscribes to level Y and a discount rules/tax rules/coupon code set Z is used. The rest is our (humans) intepretation.

For example, if user subscribes for a first time to the site or to an "unrelated" level we call it "subscription". AS calls it "susbcription" too.

If a user is already subscribed and resubscribes to the same level we call it "renewal". AS calls it "subscription" (probably with some upgrade rules applied).

If a user is already subscribed to level A and he subscribes to level B which we can parse as being an upgrade to level A we call it an "upgrade". AS calls its "subscription".

Yes, plenty! All these features require a lot of changes.

If you are interested, please take a look in administrator/components/com_akeebasubs/sql/update/mysql and look for all files whose names start with 2.6.0 or 3.0.0. They contain the upgrade SQL files with the changes.

Straight upgrade. Actually, update Akeeba Subscriptions first and remember that you need to install the Pro package twice in a row, without uninstalling in-between (yes, it's a Joomla! issue we're working around).

Nothing was charged. Please use 2Checkout instead.
