I'm in the UK and list items most days using chrome browser on a desktop computer and the glitches on the postal system are driving me absolutely crazy - what is going on with the International postage, some days it works, some days they disappear, then after trying to re-enter the amounts they magically reappear - I've tried using a different browser and even resorted to my macbook but it's the same - I'll go back to it in half an hour and it's working ok but then this afternoon I'll be having the same problems - most items I send use custom postage because they're large letter under £20, but larger items are small parcel so it defaults to "simple postage" - I cannot begin to express how frustrating it is when, in the name of making improvements, something is made significantly worse. It worked fine as it was - please stop messing around and fix it!
