Sure, I'll give them store credit and free shipping on tested Viagra when I have it.I think its a wise decision to regroup and comeback prepared. Nobody is going anywhere.
As for the Viagra I don't know what you tried to workout but most customers don't want to receive bitcoin back for security reasons. Instead you can offer store credit or replace it with your next batch. It shows that you're trying to do the right thing and it builds trust in the community.
