I AM going with the flat rate boxes. if you bid I wouldn't mind sending all of them. like I said they are just collecting dust. they will fit in a med flat rate box.
I get alteast 500 I will do free shipping. I know that is cheap but I am new and if I make a few great deals then have good feedback then it will help me in the long run.
I don't think you can close it out before the end of the auction. I'm fairly new to this too, but I think you have to let the time expire in order to get the credits.
