The seller that I was speaking with is trying to build a store page from scratch. She's currently handling a few orders from some of her previous repeat customers via email, but the fact that they're able to do this is hinged on some mixups that resulted in her ended up with their email addresses.
She does not have a way, outside of etsy, to reach most of her customers. She does not have a way, outside of etsy, to be discovered. She doesn't have a way, outside of etsy, to do business without starting from scratch.
This is a bad situation for her, because her Etsy revenue is significantly lower than it has been in previous years, both because of the changes that Etsy has made and because this year has just been rough on retail.
