Kaytee Forti-Diet Cockatiel Birdfood

My wife accidently bought the wrong bird food for our bird. We have a Budgie and this is food for a Cockateil . She bought it from Walmart for $26.99 plus tax.. Its still brand new unopened. The only issue was that she forgot to ask for a reciept and there was a small rip in the bottom that I had to tape to keep it from leaking out. I am asking $25 for it, but the lowest im willing to take is $20. so that i can buy the right kind of bird food this time Serious inquiries only. Pickup at intersection of Queen west and dunn or delivery is an option if not too far from us for an extra fee..
