Furthermore, the Sarvāstivāda-śāstra states: As for the purchasing rules of monastics, one must not demand another's goods at a lowered price; [doing so] incurs a duṣkṛta. When the robes of the saṃgha have not yet been announced three times, the price may be increased; once announced three times, the price should not be increased. The saṃgha also should not give away the robe, because it already belongs to another. If a monk obtains a robe upon the third announcement, he should not regret it; even if he regrets it, he must not return it, and the saṃgha must not return it either.
