Increase In Coinbase Network Fees

[samson516]

Has anyone else been experiencing a substantial increase in network fees (miners fees) when sending bitcoin? I've been using Coinbase for all of my bitcoin transactions. Today, I was in the process of sending $58 to one of the sponsors here for a small purchase I made and before I hit "send" I noticed I was being charged almost $13 in network fees. That's almost 25% of the purchase price!! I've sent bitcoin for order totals between $100 & $300 several times over the past few weeks and was never charged more than a few dollars for network fees on any of them. Why all of a sudden the sharp increase in network fees (miners fees)?
