Extra Shipping Label for shipping a 5 lb. box.

If you order exceeds 5 lbs. you will need to purchase this separate "extra shipping label" for your order, so I will ship your items in two (2) boxes. Poshmark emails the first shipping label from your purchase, then Poshmark would email the "extra shipping label" for this purchase. Therefore allowing me to ship in two (2) boxes. Your total shipping cost ($8.27 for each purchase = $16.54 + $3.00 = $19.54). I'm still reseraching how this works, stand by....
