fyi to users who use this for overseas transactions - card is capped at $600 annually. you can potentially lose out 2% * 1500 * 12 = $360 of cash back.
also it's the best card to use for overseas cash rebate atm, esp if you are an extremely micro person.
2% + 3.33% can effectively negate the lousy(due to visa as opposed to master) exchange rate by the bank + 2.5% visa charge.
for instance, take thai baht for eg: as of 19th aug, money exchangers are selling it for 24.4 whereas UOB is selling at 23.95 (

anyway all these for a meagre 0.33~0.48% rebate. you are of course better off spending your time earning more and be less penny wise and pound foolish.
tl;dr:
use cash for overseas whenever possible/convenient, unless you are a frequent flyer. even so, miles accumulation can be accrued through other means easily.
