Editing an eBay listing after promotion.

I listed a couple of items at the weekend when it was the 80% off ebay fee promotion. If they were to sell now they would subject to the 80%off fee.

I want to edit the listings and lower the price on these items. The listings were buy it now and 30 days long or until sold.

Will I still be subject to the 80%off fee still or will it revert to full fee with me editing and saving the listings?
