A lesson for the future, if the postage on an item you are considering purchasing is under $7.45, it is an indication that the seller is intending to send it as a large letter.  They are not necessarily being cheap, they are attempting to do the right thing by their buyers by keeping postage costs down.  However, large letter postage means minimal padding to protect the item as large letters cannot exceed 20mm in height.  If the nature of the item is such that it could be damaged by this postage method, it would be in your best interests to contact the seller before buying and request that the item be sent by parcel post,  This would mean that it can be packed with sufficient padding to prevent damage and would also provide tracking as protection for both of you.  It is well worth you paying the extra postage for the piece of mind, particularly for fragile or expensive items.
