hi need to ask you gurus on amazon shopping. i purchased some items using the amazon global eligible and got free shipping. items arrived and the courier guy called and say they want to deliver but they only work from 8.30 am to 5.30 pm, Mon - Fri only. I requested for sat delivery and the courier requested me to compensate him for his over time hours. I am a little surprised and wondered if i should pay this guy for his "overtime" hours.
