I sent down smoothie money on that invoice .. i guess the vendor has one on me ! Love it ... teaching my 13 yo about LN .. I sent him 8.00 usd for a 0.01 fee.  

 Rad.   @MaxDeMarco we found your smoothie sugar daddy    Shouldn’t have been $8 though. 

 buy 8 

 can an invoice be used more than once ? 

 Not this 

 Thanks (fruit) sugar daddy
