Any way to individualize "Sale!" text in top corner of product image?

See above site for example.

The client wants me to have some of the products say “$5 Off” and other to say “$3 Off”, but woo defaults to one message for all products, i.e. “$5 Off Adult Tix!”

Any way to change this?

I am no PHP expert, but if given some minor instructions I can hack my way around it. I have decent CSS and HTML skills as well.

Cheers,

Ian
