The academic price is basically the upgrade price anyway.
Adobe now seem to be offering two options (at least on their suites - not sure about individual apps). You can choose to have an even cheaper student version (with no upgrade rights and non-commercial usage) or the full version at academic price but which can be upgraded and used professionally.
The first makes a good offer during the course but the last is a good option if your studies are coming to an end.
Note you can only buy a product once during a 12 month period.
