Has anyone tried using Doropu?

I would not recommend. I entered the service as I saw that a $10 grab voucher was selling for $6+. However, upon purchase, there was no communication of estimated delivery. I expected instant delivery as the grab voucher could be sent online. That was over a month ago, Til this day, I still yet to receive my product.
Further, the other products that are advertised are not appealing. I have deposited $30 and haven't yet found anything to my liking. 0/10 recommend.

Have not purchased everything from there but has downloaded the app to take a look.

TLDR:
It is as advertised, but has poor UI, minimum top-up and limited items. Would only recommend if you buy a variety of products

What I like:

• it is as advertised where price keeps dropping. E.g. there's a $10 Coffee Bean gift card for sale at $1+ at the end of the day

What I dislike:

• App UI is slightly overwhelming and confusing as it is rather different from the typical e-commerce app
• There's a lack of variety of items for sale daily.
• A minimum of $30 has to be topped up before you can start purchasing. To me, this is one of the biggest turnoffs as I don't like my money to be locked in. Coupled with the lack of variety of items, I'm even more concerned if I will even finish using the credit
