Somebody recently brought up checking the tracking through one of the thousands of online tracking sites that aren't affiliated with the postal company the vendor has used.Taking Canada Post, as an example, a quick Google search for "Canada Post tracking" throws up over 60,000,000 results - the fifth and sixth of which are trackingnumber.org and packagetrackr.comI reckon you could check them through Tor safely enough as I believe the site simply relays the tracking number to Canada Post's system, then returns the result to you without you actually checking the Canada Post tracking system itself.(Do your own research on this though, as I stand to be corrected on this!)
