override language for one page - is this possible?

i have a discount that i am applying to one category which is places on a course, for that category only i would like the discount to not show at as

Authentic Confidence Workshop
Price: £90.00 £67.50
Save: 25% off

id like it to instead show as:

Authentic Confidence Workshop
Price: £90.00 £67.50
Early bird discount: 25% off

any ideas? im familiar with template overrides but im not overly sure on how to overide the language for just one category, thanks in advance :)

Zen Cart doesn't have a mechanism for over-ride language file for specific categories. You'd have to go into the display code for the relevant listing or listings and add an exception there based on the categories for which you want different text.

could you point me in the direction of a tutorial or documentation of some kind that would help me do this please?
