untrace on paper too cause the movement was through me.

I purchased the item for 450, with the condition of being paid back 450. First payment was 380, but the agreed price stayed as is and i got paid the full price.

Verifiable sales: 285, 385, 450, 600

285 was immediately resold, and 600 sale is not close to the other sales.

Taking 385-450. (With the suggestion of Lemons)
