Been using it a few weeks now hasn't really increased my sales and 50% use DC and 50% use paypal, but who's to say if those who used DC would not have paid with paypal anyway, if the choice wasn't available. I really don't like to wait a week for my money either.
I sold something last Wednesday, marked & shipped same day, Saturday funds should have been available for transfer since that is the 3rd day, however funds were NOT available until Monday! I wasn't given the option to "transfer funds earlier" because it was a weekend, so I had to wait 5 days for funds to be available to transfer, however, tomorrow is a holiday and since banks are closed, my money won't be in the bank until Thursday. That makes 8 days to get paid, had to use my paypal funds to pay for shipping and the item is in the hands of the buyer already!
I'm not liking the wait time at all, there really has to be something else Etsy can do about that wait time, come on!!
