Adobe CS3 to CS4 Premuim upgrade - where to sell?

[daynig]

Hi.

I stupidly managed to buy the wrong upgrade package when moving to Adobe CS4 Web Premium edition (for the PC, NOT the Mac).

We have Studio 8 and thought that the upgrade pack advertised on Amazon was the one I needed - especially as they only had the one and gave no details of what it covered.

We tried to install it and found our mistake. Now Amazon won't take it back and Adobe have refused to help.

We're in the UK.

Any idea where we can sell it - other than E-bay of course?

Thanks in advance,

Nigel
