RE: Displaying Savings

I thought you could add some error checking and make it display nothing if
there is no discount. If you set the retail price to zero or it is the
same as the actual price it would show nothing. This way you could have
some things discounted and others not. If the retail price is higher than
the price it would show "You save $1.00" or "You save 10%". You could
change the text to suit you needs or modify the sub so that you could pass
the text with it.

Warning - I didn't test this code, I just typed in my ideas, so it would
need to be tested.
