I have been caught by this so many times now. I am so grossly out of pocket, I have lost count at this point. It hurts to pay so much to sell something so cheaply and then get stung again by over inflated and exaggerated shipping costs. I am extremely generous with my listings but I think once my last few are closed I will be taking a big break from selling. As for courier... Not their fault that they are overwhelmed.. But seriously, they need to get real and stop accepting jobs if they can't make good on promises made.
