sometimes electrum overestimates the transaction fee, for example if your address has many transactions.
once they wanted to charge me over two 2mBTC as transaction fee
there are ways to manually select the fee, I think
Yes their is a option to do manually selection of fee,
go to tool menu, when you click below you will see preference menu click it and enter it , their below last you will see "Set Transaction Fees Manually" you just click in the box and above that first menu you can see the "Transaction per kb: in the box set the fees as per your view, i have set my fees as 0.0005 because this is minimum i am sending so that my transaction are getting confirmed soon.
I think this will help you
