Well in theory you can bid on any combination. If someone bid enough for 1 or 2 domains to compete with a bid for the whole group, i would consider peeling off the domains. I don’t see me taking $5k for 2 domains, if someone offered $15k for the group. but if the offer was $7k for all and $5k for 2, well i’d break up the set.
sorry, to not have a better answer, obviously my goal is to get the most for them, but i’m trying keep the bids quiet, to be fair, and not “game” the market.
