PH GRABFOOD VS FOODPANDA: Always compare prices.

I am dependent on grocery and food delivery services. I noticed that sometimes it is more convenient (selection wise) or cost efficient to order through one app compared to the other. Sometimes the same order is cheaper in grab or sometimes it is cheaper in foodpanda. However, this order selection shocked me. Although they have differences in discounts, it was never a price difference of PHP 200 for an order not reaching PHP 1000, THAT IS A 20% gap!!
