I bought this deal twice back in 2016 - 40 promotes for $98 (actually might have even been $78 in the good old days of $39 LTDs). I used one code as a test and the results were excellent - 15 shares and 61 clicks. I'm happy with that and can't wait to start producing the content I really want to spread, then promoting it through Quuu.
Like somebody else said below you can spend a whole lotta moolah on Adwords or you can spend smart and get Quuu promote. Your call.
