oldies but.. goodies?

This coming week I have about 20 items in my shop that are going to expire (etsy items expire every 4 months) This means that I haven't sold these prints in over four months... while some of them are my favorites (especially the vamping print) should I take this as a hint and not renew them? They'd still be available in my off-etsy shop in case someone really wanted one, but maybe when these expire it's time to just let them disappear from etsy and make way for new drawings and products.

What do you think?
