The computer estimates a shipping charge anywhere between $3.50 and $9.50 based on the total amount and volume. However, once I process the order (depending availability) and pack the stamps, I charge a reasonable fee, which almost always is less than computer estimate.
If you order several sheets (which have to be mailed flat), a lot of Plate Blocks, then the package will be sent by USPS Tracking and the charge is usually $5 to $6.00. If you order a few items which can be sent in a 1-2 oz envelope, the charge will be $1 to $2.00. In all cases, your saving from the stamps will be way more than a few dollars for shipping. Thanks for your business..
