It's a bit early for the Friday maintenance to be causing problems.

I have printed the labels directly through MyPost.

Hi BBS,

Just wondering how much My Post charges these days for 500g parcels (not prepaid satchels), and 3kg satchels?  Ta.

$7.42 500g, $12.10 3kg, $15.43 5kg satchels plus the cost of the satchel. That is the Business 250 rates.

Gee, that's quite a saving now that Ap has increased it's prices.

So I could pack something in a box and post it for $7.42?

If your item fits in a box and the box fits into the flat-rate satchel then yes.

If not, it is $7.95 for up to 500g if you use your own packaging.

Thanks, BBS.

someone posted this handy link for MyPost Personal / Business-related problems the other day - https://status.developers.auspost.com.au

you can go there and subscribe to updates or alternatively, just visit the website whenever you want to see if it's experiencing problems. apparently, around the time you posted, it appears they were/are having problems with the service.
