In my opinion if u r one of those strong players who can fight off anyone, do Plunder, chance to get 150 coupons a day. That would give u criminal status for a day.

The thing is that u recent lost to plunder.

But if u wanna get full 30 coupons. Pick the right time to do convoy when other strong players are doing some other events.

There are many ways to get coupons these days not just convoy.
