Hello,

In the sentence below, what do the words in bold mean?

He's not an easy guy to get next to. But he's flashing cash. I'm not so sure he'll let me go along on a buy.

Thanks in advance

If you are flashing cash you are letting everyone know you have plenty of money and that you are prepared to spend it.

Difficult to comment on go along on a buy without knowing the context, but the phrase is most often used in connection with buying illicit drugs.
An undercover police officer would like to be allowed to go along on a buy so he or she could get close to the dealer.

You don't need to thank people in advance for help they haven't given you.

Hello RonBee,

I don't know how to write in English, so I use some "recipes"
I am like a child learning. I won't write 'thanks in advance' anymore.
