This is pretty much the same as the very.co.uk new member codes out there (it's the same company), which normally we wouldn't post here. But since you can pay via PayPal, I thought this one is worth looking at. Just be aware that they have tried shenanigans in the past with trying to retroactively disable codes, so while it might be worth a punt that's something to bear in mind.
However, definitely don't try and register for another account to use these code again if you've already done so in the past. (I think they're doing address based checking to prevent this, which is why some people aren't able to place an order.)
UPDATE: Woolworths got in touch and asked us to remove the codes.
