Salut,
Back in october 2017, I wrote this post why-purism-should-send-an-contribution-document-instead-of-an-invoice.
Would not it be much easier to get one official document from the company that is certifying that we did contribute to a project by making a donation (wich we did for what I recall) and that the content of the parcel is a reward for it.
Is that so hard to do?
Beware Purism! Winter is here and the call for a refund is getting clother and clother…
