Change.io (change.io)

It's not clear to me. So it's $79 per month or per year or forever?

Also, who will add the items to be for sale?

So the store manages its items for sale. The first thirty days are free, and it is $79 / month after that.

This info is available on the tour page [1]. I almost think it would be better if the tour page were the homepage. Would probably lead to more conversions.

The domain name is what I like.
