Thank you the info, but just to clarify:
Cannot anyone see TXIDs, since it is all the same address they have to send to?
E.g. this 0.05BTC with this TXID has not been send by me, but how would they ever know that if I just mail this TXID?

I understand of course we don't aim at cheating...
polymerbit would notice two people using the same txid, he would then know something was up and request that both people sign a message from the sending address. only the real sender would be able to sign.
Exactly this. We will keep a close eye on the BTC coming in and the associated addresses.
Each order will have an associated TXID. We are building a spreadsheet for it.
That is why we need your order number. We can then match all. And see who is outstanding
