I spoke to Q Card today and they said it was Trademe's decision to stop using Q Card. Not even Q Mastercard, it seems. 

Well, I just went looking for a product on TM, found it and it looked a bit expensive, and of course, no Q Card so I had to look and think about it a bit harder. Then I remembered I have an Ebay Oz account, so hopped on there and found the exact same product. Less expensive including shipping, so for the price of one on TM, I got three! I may have gotten it on TM if they still supported Q Card, but TM's loss. So since I have to pay straight out of my pocket now, iImight as well buy what I can off Ebay rather than TM.  Trademe, I think your future looks bleak when you don't care or listen to...

Well, this sucks. I guess Trademe are discouraging consumerism so people don't overspend on their Q Cards.  LOL  Hey Trademe, seen a drop in transactions yet? I know I won't be shopping as much on Trademe since there's now no difference between outright paying from my bank account as using Ping/Q Card.  The ability to use my Q Card at several retailers has made my life a lot easier, e.g. Repco, Bunnings and until now, Trademe.
