remove it from the hustler list and put it in the MC for 7.5-10 mil . Instant sp sink :)
Hiiiighly doubtful. It's a donation item (as well as an achievement item) and cash shop items should not be placed in sP-only areas.
or have a MC chance bag that one previously retired cash shop item 'retired' being the key word . One non-transferable feature (random) eg: 3-5 all stats/1 week GA/sbpb/etc and one chance bag item of that MC item :) price at 12-15 mil .
While the idea is pleasant, since I fail at saving csc 90% of the time, I doubt that will happen as well. It is still in a sense cash shop items going strictly for sP. It is one thing to buy an item from another user and another for the site to physically place cash shop items in an sP-only place.
