I use a CasperVend terminal for delivery of some items. It shows a lot of items which I never bought through Casper, but from MARKETPLACE. This is not mentioned. In stead it gives an error and some suggestions about possible causes. The real cause is not among them: I never bought those through Casper! When I realise that, I go to Marketplace and... can still get the items redelivered that were 'no longer available'.
