Dear Customer please take note that Normal mail have to wait up to 3 weeks because Singapore have inform us that
1) they don't work on Saturday , Sunday and public holiday
2) in the event if the pick up truck is too full, they will pick up the item the next pick up time which is the next day
3) there is a reason why Singpost ask for extra money for AM mail, Smart pac and registered mail because they will sent out those mail 1st, follow by they will sent out letter ( cause letter normally belong to company or government who will sue them for late delivery. Lastly is normal mail parcel which is us
4) Singpost will pass the items to the auntie or uncle that will do the sending on bicycle , walking or car and if that day , there is so much letter and registered mail , am mail , smart pac in that area you stay, you will have more delay cause the number of worker they have is fixed so we must understand that for the best price, you have to wait .
