In our country, they will send you a notice in the post when a package has arrived. And then you have to go queue at the post office to receive it. However, every week I now find myself queueing at the post office just to see if any candy packages might have arrived.
I think the twice a month deliveries are great as they are still pretty far apart that you aren't sick of them yet. Lately the packages have increased in size and its a good size to make it enjoyable but not put you off sweets for a while.
Bemmu - You mentioned that a lot of people have un-subscribed, is this after you have changed from using an envelope size package to the new larger box?
