I looked at something the other day and it said "does not post to NSW". I thought it strange, then thought maybe sellers were finally able to specify which areas in Aus they didn't want to post to......like plant sellers who can't post to WA or Tas. Seems I was wrong!

 

As for not being able to specify letter rate, isn't that what the flat rate postage option is for? I've never had any issues specifying that postage is $1.40 or $2.10, or whatever, when I've used the flat rate option. Stupid CS!!
