It's a loan shark add that can trade either way, buy/sell.
If you are a home owner here in the US, you have experienced loan sharks sending you a good check worth in thousands of dollars(depending on how much morgage you have already paid off). By endorsing the check, you have accepted & are liable to all terms & conditions on the back of the check and attached letter, which is usually a very high interest rate, and other shark-like clause.
