Hello FTer's.

Suppose I am MSing with Friend A and Friend B, with $300 transferring among us and $0 in our amazon accounts.

Scenario: Suppose Friend A sends me $300 at this second. Being the "middle person" - how long should I wait to withdraw the $300 into my personal banking account, then send a new $300 to Friend B with my rewards card?

I don't wanna raise suspicions ._.
