I agree that they are really bad, but eBay won't read here, and they don't accept suggestions anyway.

I wish sellers gave buyers the opportunity to pay more for a better service.  They could at least offer the choice. And if they are using Aramex, they should clearly indicate it in the listing instead of just indicating "standard parcel delivery" or "free postage". I have to ask every time now if I really want something, otherwise I will just pass.

There is always a problem with them, and I do try to avoid them, but some sellers indicate AusPost and then use Aramex, and international services now very often use them as the final local courier (for example the new international service offered by eBay).

Either they lose parcels altogether, or they leave them unattended downstairs in an apartment building, or they keep parcels onboard for delivery for something like 2 weeks (not funny when you know they are going to leave parcels unattended downstairs, so you have to be home and refresh the tracking every ten minutes or so), or they take over 6 weeks to deliver from Sydney to where I live (about half an hour by car).

The last time I bought from iHerb, postage said they used either AusPost or Aramex (in the past it was only AusPost), so I had to ask them to please use AusPost... Luckily, they complied.

Sendle is good where I live (they take 2 days to deliver from Victoria to NSW). Luckily they don't use Aramex, but it is a bit of a risk because in some areas they do, so as a buyer I am fine with Sendle because I know they are not using Aramex in my area, but if I were a seller I would avoid them too, just in case they use Aramex and then buyers have a problem and are angry.
