There are many players with little of Maple Story mesos, although they are above 70 levels, so I want to give some enlightenment to them.
You can open store to sell your goods. You do not reluctant capital. You need have a good location to open the store to gain Maple Mesos. You can not sell your goods with the lower price in the bad location.
If you only play the monsters to earn Mesos all the time, you never concern about the market. You can keep all the equipment form the equipment. Then you can go to open one store to sell them. You can mark a uniform price 50w Maple Mesos and you can sell 20 set of equipment, that is, you can gain 1000w Maple Mesos at least for a day. So you can get millions of Maple Mesos for a week.
The next way is to make a businessman. The easy way is to resell. The cost is 1 E Maple Mesos at least. You can collect some goods which can be sold and be collected easily. The shortcoming of the way is that you can not collect all kinds of good things. So you need spend more time to purchase the good things. Sometimes you can 500W Maple Story Mesos than high-priced to sell products. You had better collect goods to sell. You can get the books, but many players have the common question how to get books for a short time.
You need go to get books in the appropriate time when have not many players to play. In general, to get books is a very good way to earn Maple Mesos. Many players become the rich man with this way. Of course, they have a good luck in the game.
