I don’t know any sites exactly like that one, but my go-to is
It’s a price comparison site across the 23 major online stores, and you can search across 4 auction sites.
That might be closer to what you’re looking for. They are about the same, but they also have coupon codes and discounts. I don’t use them because, I think, you have to install a Chrome extension to click through to a site.
Every site has it’s own coupons, discounts, and brand deals, often for specific days or time periods. Plus you get points, coins, or whatever they call it following whatever rules specific sites set, and you can points for using specific payment methods, or combinations of such. For example, you might have a coupon for Shopee that gives you back 10% of your purchase in coins and your credit card might give you 1% cash back, or you might buy with LinePay on Momo, and get 2% in points from LinePay if you use one credit card, 3% if you use another. Your might get a better deal using your credit card directly. It all depends on who is doing what deal on what day with what site and with what combination. It’s a bloody headache.
I’ve found it best to pick a few sites and use that as a go-to. For expensive things or rare things I use FindPrice. I use Shopee most of the time and LinePay for places that accept it. Shopee has become annoying with their irregular deal events with coupons good for one day only and some good for a few hours only.
