# MAPE is high for daily sale prediction

I have daily sales data from 2011 to 2013. I have to do prediction for 2014.I have used arima and exponential method to predict the daily sale, but it is not giving the better result. MAPE is around 25%.

y=ts(x,frequency=7)

fit <- auto.arima(y)

fc <- forecast(fit, h=265)

plot(fc)

fit <- ets(y)

fc <- forecast(fit,h=265)

Below is the link for data:
