1. Make individual orders small enough to fit in your std mail box.

2. Have them sent to correct address, but wrong name (that "return to sender" game)

3. No signing, etc.

4. True, you can not track the
package...but if you want to be really safe...why not. The volume of std mail is so huge the only way you would get intercepted is if the package was broken open. In that case deny deny deny....

Am I missing something as to why express mail is used...or are most people too impatient to wait so long for their orders.
