I've just received an email stating I need to update my returns policy, or items will not be auto relisted 

Currently 7 days, (as I always thought the buyer will know within 7 days whether it's broken or not as described), but now need to increase to 30 days.  Peeves me a bit as I only sell pottery, so now if someone breaks something within 30 days they can get a refund.  Though I guess I could argue that it can't be returned in the condition it was sent.

Anyway I would have thought I could do this from Site Preferences, but I can't see where there is the option to change the return time.  And I really don't want to have to change each and every item one at a time.

So it would be appreciated if some members could steer me in the right direction.
