where does one make a suggestion for ebay flat rate large letter envelopes

....to Aust post or to ebay?

500g satchels works well for items thicker then 20mm but would be too expensive for buyers to consider them for posting a magazine.

3kg satchels are always good value for combined postage.

It would be just spot on for me if you could send off printed matter that weighs up to 250g and up to 500g with tracking for the price of regular postage or cheaper.

As to your actual question, why not post your suggestion on Australia Post's facebook page?

I posted on AP's FB wall, heres their reply...

"Absolutely, this is the right place to make a suggestion for new Click and Send products. I have passed your feedback on to the Click and Send Line Manager for consideration.

Thank you for taking the time to let us know.

I would like one in between - 500g - 3kg is a large difference.

How about a 1.5kg ? If you find out where to ask joz, can you throw my question as well?

Wrote in to AP feedback, suggested a C&S 1.5kg satchel and up to 250g small parcel in satchel form.

also up to 125g large letter C&S including the other weights.

Hope they at least consider large letter C&S for the time being. Not tough bags with bubble lining just plain paper envelopes to keep the costs down. Most sellers water proof printed matter and back it with cardboard anyhow.
