Try running a few auctions.  This will bring listings to Page 1 in most cases, and it may draw lookers into your store.  It is a matter of trial and error when to finish them, but I find that at night gets a reasonable response.  I think you would get a good response on auctioning the bags especially.  Start them at what you have them listed for now, which is good value.  And list some more of them, they are a great idea.
