Lynne,
You might try visiting the websites of dealers in used guitars. Two places to check are Elderly Instruments and Mandolin Brothers (they sell lots of guitars, too).
Manufacturer's websites seldom give prices for their product.
If you don't find it at these two sites, try a websearch using words like "Epiphone acoustic guitar used".
Good luck in your search. There may even be a Mudcatter who can talk to you about prices.
