+**Eurobuch Website (Complete):**
+- Shows all 35+ offers
+- Price trends & history
+- Press `Enter` on any result

+- Subsequent searches are faster
+- Check internet connection
+
+### ISBN Not Recognized
+
+- Ensure ISBN is 10 or 13 digits
+- Remove any extra characters
+- Try both ISBN-10 and ISBN-13 formats
