First, you will need an EZbuy account, it will be really worth it. Best part, they have collection point from Canteen 2 in NTU!!
Buying from Taobao /EZbuy won’t guarantee the quality, occasionally will you receive item that doesn’t work but they are CONFIRM 3X to 10X cheaper than Simlim Tower.
Waiting time is anywhere from 5days to 3 week (5 days only if you are really lucky that the seller send your order out the same day and it finished inspection the next day in EZbuy warehouse PLUS you used Express shipping which is $2.99 per 500 gram) if you are REALLY UNLUCKY that the seller gone MIA after you purchase, good luck, but that shouldn’t happen with the link I gave as I bought from them and all is good.
