I was overweight by 3 lbs by AA scale, 1 lb by my own 2 scales (hand's/portable and digital bathroom scale), and 1 lb from Secure Wrap's scale, I doubt that the plastic wrap could weight more than half pound. Anyway, I'm just asking for a partial refund, money that it belongs to me.
I will wait until Monday, otherwise I will have to dispute the "extra" charge.
