Invitatio ad offerendo (invitation to treat/bargain) vs. offerta ad incertas personas - google it, maybe it will be helpful - the principle is quite similar to what you've got here. They basically say that they will do that, and that the conditions will stay the same, i.e. they cannot later offer a different price, or to say that they do not want to repurchase it.

First right of refusal? AFAIK the 'unwiderruflich' does not imply any right on the part of the company (asssuming the company is "wir.") It means that this offer does not expire. If there is a right of first refusal, it must be expressed elsewhere. Or is "wir" the customer?

Dear contributors, first of all thank you so much for your ideas so far, it's so good to be able to share the 'knottiness' of a term with colleagues. The original is ambiguously phrased and is meant to express that the company has first right of refusal to repurchase items bought from them by the customer in the first place. 'Irrevocably' sounds odd to me in the English version of the contract. Hope that helps and thank you for contributing!
