[quote name='Gamer SDP']got invoice but never got confirm about costs (asked why shipping cost was a bit high)[/QUOTE]
Really? My two options were Media Mail (really cheap) and Parcel Post (Prices vary depending on how far its being shipped). You can look up product weights on various websites like Amazon and get an idea of how much Parcel Post would cost depending on how many zones it has to cross. Media Mail is about 80 cents per pound it seems. I think delivery confirmation purchased online is another 90 cents.
I picked Media Mail with Delivery Confirmation. Got my Delivery Confirmation tracking number 2.5 days ago, but it hasn't been updated, which isn't entirely unusual with USPS Media Mail. But I'm hoping something updates soon from the USPS end, assuming the package has actually been dropped in the mail and its more than the shipping label being generated.
