I've been shopping with Zalora.com.ph for as long as I remember.
If you buy from their original brands and affiliate brands ie. Zalora, Zalora Basics, Mango, Something Borrowed, etc. (not individual marketplace/boutique owners), you will receive your item most likely the next day. The boutiques take longer but it's alright. If you ask for an update, they reply right away on working hours.
Payment is a breeze: I tried Cash-On-Delivery (COD), credit card and paypal and they all work well. Returns are also easy, just drop them off at your nearest accredited LBC or 2Go. I hope they continue their superb service and discounts. Kudos, Zalora! You make online shopping not stressful at all.
