I just switched to Managed Payments.
My listings have fixed fee for shipping within Canada and another fixed fee for shipping to US. I used to select the one and only delivery service I include as part of the flat fee.
Now since I moved to MP, it all changed for my buyers. My buyers are presented with what Ebay things should be the rates I should be charging because ebay things I should purchase Ebay labels.
For example, my shipping is flat 15 CAD
Ebay ignores that and instead gives the buyer the options:
Shipping standard ... 18+ CAD
Shipping expended ... 22+ CAD
Shipping express etc...
I am OK with Ebay giving the buyer more options but why ebay now completely ignores my setting in the listing, which was Standard shipping for 15 CAD.
Of course that dissapoints the buyer who now has to pay 3 dollars more effectively for the same shipping service.
The reason I charge less for shipping is to be competitive and secondly I do get better rates (I don't ship with Canada Post.. Ebay somehow things I should be thrilled with Ebay offering me their Canada Post rates).
