If you're looking to buy a melon sword with a payment plan; goodluck. Unless you are offering 600k in say 2 weeks (the high price due to the length I have to wait for my money), I personally would never do a payment plan. The only exceptionis that if you were a good friend and I can trust you to provide me with 400k in one week without complications. The reason is: I don't like waiting for my money. I am a person who likes to buy and sell in a quick manor so that I can continue making money and I'm sure that other people are like this too. I know you didn't ask for this, but I'm basically implying that it's better to wait until you have the 400k, than wasting time trying to get a payment plan for a melon sword because you will find out that they are hard to come by.
