I like that it is constantly updating in real time so there are never too many deals out at once for me personally! Sometimes they have some minor hiccups but nothing serious enough where i wouldn't use them again or recommend friends get their Camel Cash app (which has all these great features).
It's pretty cheap as well compared with other more expensive options available online such credit card rewards apps which gives better cash back percentages than this one does sometimes if not always even then still worth using especially because its free :) Its very easy just scan your barcode from any product page anywhere whether grocery store/restaurant etc..
