There is a known glitch where listings are not expiring the way they should. In fact, they can go years without expiring. Several people have stated that when Etsy finally discovers it for their shop they charge all the back listing fees at once, and change the renewal dates for the impacted listings to figure from the day it was discovered.
Totally messes up people's finances, and all the work they did to spread their listings out for staggered renewals and traffic.
Once again, your friendly neighborhood Etsy screwing sellers royally. It is their mistake, it should be their loss. Sellers need to complain big time.
