I am using it and have had 3 or 4 sales from it. One on the very first day! The sales have been automatically deposited to my acct. on Monday.
I think it will increase sales, because I have had a lot of people say they don't have or don't want paypal,. And they didn't understand that you can still pay with paypal via a credit card without signing up.
For a $20 scarf, these direct etsy fees are about 10 cents cheaper than paypal.
I was worried, too, that I don't get paid until it ships. But when you order online from any company, they don't bill your card until the item has shipped, either. Plus, the customer has paid, it's not released to you until then. It might make a non-internet-savy-person more likely to purchase.
Once a week is fine for me to deposit funds. They say you could increase this if you want to. If I want to withdraw from paypal and deposit funds, it takes almost that long until it shows up in my account.
So, so far, i am quite happy with it. Easy to set up. Easy to use. I like it.
