Please take a look at this internet chat between a seller and a buyer;
Buyer:Already paid 19,75 +16,75 = 36,6 So I have a credit of about 11 USD, if you could add the watermelon split 7" it would be fine, if not paypaled 10,5 to me.
Seller:Sounds good, let's hope that it doesn't push the weight to much.
Seller answered after he had checked the split's weight :I WILL be including the watermelon split7".
My question is why future continuous ? Why not simple future or present progressive It is a kind of arrangement as I asked for it first.
