I have been having a sale of 20% off on all items I have listed, for 30 days. What has happened is buyers are sending me offers that will end up to be less that the 20%, because the heading of "Extra 20% off". No where is there a message that the item is on sale for 20% off. Suggestion: buyers are always looking for a sale, though the headline says nothing about a sale. How about a sub headline that the is a x percentage off sale going on at that time. NOT "extra 20% off" without a explanation. When you receive advertising the first thing you see is sale xxpercentage off. My customers would not need to take the time to make a offer, if they had noticed a "SALE" was going on. I received several offers and sent the potential buyers a message that there was a sale going on. How especially when their offer was less than the percentage I was already offering.
