I think you need to have some patience. If you want  a reply to your query (which is already answered multiple times in meta) in 10 minutes after posting your thread, this is not going to happen. Also note that the members are helping you for free and most of the senior members are here just in their free time only. If you cannot wait for some time to get a response, how will you be able to survive the shortage of merits (merits getting halved as per your opinion). Regarding your question, there are merit sources who get some merits to spend every month.
