The best and classic way to marketing is buying and selling items. You choose when you will use the board or the market to do so, sometimes is better to buy or sell using the market, sometimes not. For it you have to start with a decent amount of toricredits. (How much)

When you are willing to buy an item, be sure you are offering a good price, in order you can sell it getting profit in the future. If you don't know either how much an item worths, you should do some research, then you avoid overpaying for it. I am not sure if Toriprime &VIP allow to search items price on market board, if so, it is a good way to know about the item you want to buy/sell, otherwise you can post in the price check megathread.

Log all items you buy or sell including the price they cost. It will make that the things get all registred and organized. Not to mention that it helps when you will sell an item and don't remember how much you paid for it, so you can just check the log to know.

Never sell an item cheaper than you have bought. If you notice that the item will not be sold for the price you want, in any circunstances, even for the price you bought, then you can put it in the TLDRsack for we use in our events/tourneys. Its better to sell losing toricredits.

Try to keep ~equal the number of sales and purchases, so that you can have a reasonable amount of TC to take some opportunities that may appear ( e.g An user want fast TC and is selling his stuff for good prices). Try to be fast on those cases.

Regarding the profit we get from the marketing, a % ( how many) of it should be sent to the vault for promotion of events/another stuff the clan need to do. The rest of the profit must be maintained for keep the things running out.

Overall, follow the market rules and always be careful with people who come with strange stuff. Check if the guy has the TC/item he is offering to you. Anything that breaks the rules you should not backseat moderating, just use the button report. In case of scam, tell us what happened before posting in the scam reports board. Contact the members of the clan if you have any problem you are not sure how to act.
