Where do you live? Bank wires are pretty expensive everywhere I've seen. (local bank transfers like ACH are free on TW too)
EDIT: 32p - https://transferwise.com/gb/pricing/borderless-send?source=G...
I apparently have to pay €0.28 per transfer in EUR with Transferwise. There are competitors (both in CHF and in EUR) that do this for free. I do something like 8 transfers per month, so that's 8*0.28*12 = €26.88 per year, for no added value. Not convincing.
