I fail to see the advantage of signing up for the powerseller discount. In fact, there seems to be a disadvantage. Maybe I misunderstood something, but I had a lengthy chat with Canada Post about it, and I was told that you get a level 2 discount on domestic shipping, BUT you have to meet a quota of 1,200 packages (I have the same level on a 1,000-package quota). You also get a level 1 discount on international PARCELS (not small packets). The requirement to meet the international level 1 is normally 100 packages. I failed to ask what the quota was for those who signed up for the powerseller discount.
If what I was told by Canada Post is accurate, I would have to ship 200 more packages in a year to attain the same discount level I already have (on domestic). The level 1 discount for international I also have.
Furthermore, there seem to be some additional restrictions when compared with having your own business account. One is that you are obligated to use their EST to get the discount (we don't use it), the other (I think) is that you must pay immediately, not billed afterwards.
If you already have a commercial account with Canada Post, it would seem a big mistake to enrol on the powerseller discount. Your current contract will be void, and a new one will be issued instead. You may find you won't like the terms on the new contract.
I don't believe the 30% discount bit.
Commercial Pricing levels for Small Packets exist, but only if you ship 50,000 packages a year. If you're in that bracket, you'd be extremely foolish to sign up for the powerseller discount (which buys you absolutely nothing as far as small packets is concerned).
Maybe I'm all wrong, but as far as I can see, the powerseller discount is just a lot of hoopla about nothing.
If you're considering signing up for it, better give CP a call (1-888-550-6333) and find out what exactly you're signing up for. Otherwise, you may get audited a year from now and be told you owe a ton of money because you didn't meet the quota you committed yourself to.
