food for thought: There is something called Regional A boxes--Regional A priority box will fit about 15 of these. Regional A boxes are available at the post office cust service counter only or online--they are free for the boxes and the tape. The shipping is then only $7 anywhere in the 48 US states--25# limit. I use them all the time-bc they are so cheap..they also are flat rate but regional means cheaper for you and your customers--just wanted to share some info--no worries--maybe the next auction...take care
