I relocated here from Italy 1 year ago and decided not to ship anything,
it cost a lot and not really worth it...
unless you're talking about sentimental value.
I think it'd be easier to get the stuff when u get in SG, didn't understand if u already have settle the housing part...
it's a good idea to stay light on luggage until u find the proper place.
If u need to save money u can look at second-hand stuff, there're lot of stuff and often in good condition (I often check the local gumtree website before going for the new one).
As already said above, imported food is pricey; in my case I get easily used to local food and from time to time I ask someone to bring some food from Italy (like when colleagues comes in a business trip).
Electronic goods aren't pricer, I think nowadays the globalization brought same prices worldwide; there're little differences based on the applicable axes (e.g. in Italy the GST is 19%, here only 7%)
Again, my suggestion is: don't bring with u lot of stuff and wait to be here and better understand ur need
