Main difference between the two types of shipping is price, how soon you need the product and day the item is delivered.
Normal/Standard delivery is basically normal postage, you will not be notified of exact day on which the package will arrive, so as a consumer you will not be able to track how the product is delivered. However, in SG this shipping is safe and within 1-3 day time frame you will get the package.
Registered shipping is a bit of a more costly, you will have the ability to track the package on the Singpost Package using the delivery receipt which we will provide to you. Invoice is sent digitally, however, since we have to post package manually shipping receipt is not set and dependant on SingPost rates, given that Wix does not have proper shipping integration as yet in SG. However, this option in SG takes same time frame to reach your doorstep but is more costly.
Only thing that is similar in two methods of shipping is the fact that package will come to your doorstep or mailbox so there is no need as such for you to go to SingPost Office.
