I pay my board fee in cash. Board is $180 + GST per month (=189.00). I'm very lucky my barn owner is extremely understanding, because I pay $200 one month (to cover 2 months of GST because I hate having to find change) and $180 the next. I alternate, he's never short money and it makes it easier for me. We all win!
If given the option though, I would love to pay via Email Money Transfer. Not Paypal. I hate PayPal.
