Please take a look of updated one
I'm getting error like unable to marshal value
I made all class Parcelable. how to send its object through Intent
Thanks in Advance

Logcat is like

Answer

You need to implement Parcelable also in the Item and Coupon objects.

Then when you add and read the list in you MakeOrder class:

@Override
public void writeToParcel(Parcel dest, int flags) {
    ...
    // to write the Item list
    dest.writeList(items);
    // to write Coupon object
    dest.writeParcelable(coupon, falgs);
}

BTW, your constructor is empty

private MakeOrder(Parcel in) {
    ...
    // to read the Item list
    items = new ArrayList<Item>();
    in.readList(items, Item.CREATOR);
    // to read Coupon object
    in.readParcelable(Coupon.CREATOR);
}

EDIT:

The where more Percel problem added to the question.
