We bought volumes:
Sai no Kami 5 (so we can finish this series when we get that far)
Harigane Service 3-4 (because there is fundamental lack of magazine chapters)
Hana-kun 9-10 (so we can finally move without pressing on chinese translators and don´t need to clone out watermarks)
In download tendencies from last half a year or more, we earn enough to buy 1 volume after 3 months.
We don´t have that many series for which we need to buy volumes, so it´s not so bad
Poll to decide for which series will be bought volume as next -
