Once upon a time, parcel post was the way to mail packages.
Now, it's a good idea to check both priority and parcel post rates.
I am going to mail a package that weighs 52 ounces from Minnesota to Iowa.
Going through PayPal - the cost for priority mail will be $6.98. The cost for parcel post will be $7.52, plus I would need to buy packaging (Tyvek envelope)
I was surprised.
