So I've recently started selling video games on TradeMe and it's been going well, now I'm looking for ways to cut postage costs. This is how things are looking at the moment, my postage options are:
$5.00 C5 Parcel Post Tracked (includes bag and postage)
$4.00 C5 Parcel Post Tracked (postage only)
$6.70 A5 Courier Post (bag and postage)
So I have a choice of PPT or CP which includes the bag... or I can go to TM and buy bags in bulk, then put the PPT stickers on them, cutting costs. The problem with this is that the max size for C5 bags is 165x235mm and I've only found bags for sale on TM which are 190x260mm. I've also looked at buying courier bags in bulk on TM and putting courier stickers on them but that's prohibitively expensive.
From the looks of things, the best bet seems to be just use PPT and CP (bag and postage) for now, then when I am selling more games to call NZ Post/Courier and negotiate an account with them... any hints on how this works and how many bags I would need to regularly buy from someone who has already done this?
