To answer your question about why it won't let you lower days :-) once a bid has been placed on an auction nothing can be changed. The only exclusion to that would be upgrading the shipping to a reduced price or free if there is a shipping fee. Also once you receive your sellers wings badge which you will get after so many successfully completed auctions. You will be able to set a GIN option which means Get It Now. For a fee of credits you can set a specific amount of credits you would be willing to allow a bidder to select to instantly end the auction for that amount. Welcome to Listia it really is an awesome way to trade items that we don't want for credits to get something you may want or need! Best of luck on all auctions both selling and bidding on! Have a very wonderful day!
