There may be several reasons for this:
a) Players have different levels; they participate in different events, and some offers are event-oriented.
b) Some offers are personalized and created based on account history.
c) The event offer may have already been purchased (e.g., in the in-game shop).
d) The offer may have been time-limited, and is no longer available.
I can't see an offer my clanmate can see.
