Quoted from KozMckPinball:Something to watch out for. If using Buy It Now to get the item, eBay makes you commit to buy (clicking that described button) BEFORE you try the discount code. If the code does not apply, you are still required to buy it and will get hounded about it until you do. Unfair business practice just be aware.
the current 20% off discount applies to select sellers - doesn't appear to apply to all sellers.
