Do not use FEE too small For Large Transaction comrades I do not go in for 1 month. 
Dammmn longest time I had to wait was 10 days but luckily coinpayment noticed the transaction and told the merchant funds received so he sent my package. It didnt confirm on blockchain 10 days later which was wierd. Tried goofing the system a second time and it didnt work confirmed last 2 hours before it expired then coinpayment said funds received.
