Not to sure how "Plaza" is from a Google "Top Developer" but this app spammed my entire Facebook contact list without my permission as a fake request from me to install "Trusted Local Classifieds". Reported it as Inappropriate and I hope it gets pulled from the store.

I use the Favado app that does just that. You can search for a certain food/item, and get price comparisons from all local stores of your choosing. It also provides the stores' weekly flyers.

It's an app/website called 'Mercari' actually! Are you sure you got the right one? Can always stick to the website too; no idea if it's region-locked.

They may then choose the gifts they want to offer. * In your Kidilists, check the gifts booked by your friends and choose the gifts you want to purchase. Find its out in « My purchases ». Any feedback is appreciated.
Saw a discussion of a similar kind elsewhere and it seems like Razorpay has a solution to this. The link to make the payment is sent to the customer's phone. Agreed, it means that the customer needs to have mobile internet to be able to use it, but it takes away at least some of the worries of having a keylogger or fake app installed on the shopkeeper's phone to track card details.
PS: I'm in no way associated with the product.
Check the shopping list and fridge organizer Fridge and Shopping app. It operates with a grocery item price/expiration date/how much is left.
I you have questions about this app feel free to ask me.
