@NogDogFeb 07.2006 — #It formats the value of $price_out to be a string starting with a dollar sign with the following number rounded to 2 decimal places and with left padding up to 3 digits (which then gets trimmed off by the trim()), followed by the word " off".
A much cleaner and simpler version would be: [code=php] $price_out= sprintf("$%.2f off", $price_out); [/code]
