This is my Canpar horror story. I was expecting 6 boxes of t-shirts from a supplier and I needed to have all 6 boxes for a major event, but only 2 arrived on due date, which was a Friday, that
was one day before that event. I called and asked why I only received 2 and was told that sometimes boxes end up in different trucks and I should receive it on Monday or Tuesday, which
would be 2 to 3 days after that event. I asked why would 6 boxes that have to go to the same address and are part of the same order go in different trucks? I got a stupid answer,
and I let it be known to that customer service moron. I ended up getting all 6 boxes delivered for free, but ended up losing a lot more money due to their lack luster performance.
Since then, I never allow my suppliers to send with Canpar. This was a win for UPS.
