After Uber pulled out, Grab stopped handing out promotion codes that would save you anywhere from $2-5 bucks per trip (or occasionally more), and they slashed the rate you earn reward points for every dollar spent by ~13-16 times.

Grab became the market, quite literally. It's such a drastic change in just a matter of weeks, and what makes it worse is that there is practically no competition in the ride-hailing scene over here (for now, at least, and hopefully).
