I never had an issue with CP, ever. I've received/ but mostly sent at least 200+ parcels with them. Never had an issue on my end. I use them because they are convenient and relatively economical (1 minute walk from my house). Went to FED EX a few weeks ago to send out my PTW, $90 to Calgary in 4 Business days. Kinda steep, but I didn't care, I didn't pay for the shipping.
But its true, other than my Visa/Rogers bill(which I check and pay for online anyways) I don't really get anything important in the mail, up until recently the Cert's from RCMP.
Although my Mesa Tactical Shotgun Saddle is stuck in lingo
My neighborhood mail box:
There's always a garbage can there purposely for the junk mail and its usually pretty full.
