What if buyers don't have a credit card and not in your area to pay cash for pick up?

Paula, this issue is a trademe searching issue, not a bidbud issue. IE; your auctions appearing on bidbud has no effect on the search not appearing on traeme. A lot of people only use bidbud to buy items on trademe as it has better bidding and searching tools. If you are wanting to sell stuff, why would you not want your items appearing there for those buyers, your just taking away some potential buyers. Doing this, its not going to help the searching issue on trademe for your auctions. 

Paying within 24 hours is the perfect buyer in my eyes.

Many, many years

Some don't read the prices correctly, some try to get out of paying the extra and for some it's because different courier companies treat some addresses as rural and some not. Either way, don't send it until they have paid the full amount

@honornz247 - note the ping fees of 2.19% apply both on the item and shipping cost, in most cases work out cheaper than the 7.99 success fee that WAS charged on the item. So just looking at it from a pure financial perspective, it doesnt benefit trademe more than you as they receive less in fees

Andrew Of all my trades, Ive only had 1 trader that argued black and blue that they werent rural. I sent them the outcome of the rural checker website mentioned above and they still didnt agree. So I just gave them the choice of choosing a different address that was non rural, pay the rd fee or i cancel the trade. They eventually gave me a non rural address. Now - this is my experience.  im just telling you my experience. Its just different from you I've been on the community forum for years and Callum and flossy63 have helped me with great advice, as they have many others.  

No, signature is not required. You're responsibility is to get it delivered to the buyer and NZ post has provided you with the evidence this has happened - so you have fulfilled your duties. The item has either been stolen (this is the buyers issue assuming nz post has followed their obligations re where to leave), someone in the household has taken it or it is a scam. Ive had people in the past try to say it wasnt delivered and demanded a refund only to provide them with photo evidence from the courier and then they go all silent

I wouldnt refund. I'd also be tempted to ask them to lodge a claim with NZ post for compensation for the lost item. Knowing full well that nz post wont (as they dont with anything sent with stamps), but it sends a very strong message where the liability sits now, and that it is not with you

There are definitely ways traders could abuse this, however I have at times asked a question and then on second thought didnt need to or had a change of mind  - so for this purpose it saves the seller time needing to reply. In terms of the proof argument, you can still receive emails with the question being asked, or the answer to the question so as long you keep these then you have the proof if needed. I think like most things, there are some genuine benefits for those honest ones, but also open to abuse for others
