I hope it is free shipping now because $10 is way too high for shipping on an item like this. It's only approx $3 to stick it in a manilla envelope and mail first class.
you cannot charge $10 for the shipment of a videogame per Listia Rules. Shipment of one game in most states with Delivery Confirmation is $2 and even if you charged $1 for the envelope that would bring it to $3. You should lower your shipping cost prior this being brought to the attention of Listia Mods.
