The difference is that when people pay with credit cards you have to pay a processing fee. I think it's 2-4% based on how much you use the service. So, if you offer a discount for people to do a bank transfer rather than pay with a credit card, both you and the client are saving money.
I don't do mail.
That's why I have checks sitting on my counter. I mail about 3 things/year and they usually take months to get out the door. I don't even own envelopes, much less stamps. I'm not sure what you mean by electronic deposits... I would not be comfortable giving my bank information to anyone.
Also, just so you know, my name is not Bette. I saw that before but I wasn't sure if you were directing it to me or not. My name is Amanda. My ID is VagabonD
etteVA which shows my female vagabond ways which I'll fund through being a VA.
Just thought I'd let you know. No biggie.
