Hey guys, probably a dumb question, but was just wondering if anyone knows of any website/app that has the ability to compare prices of specific grocery products from the various major supermarkets? So, say I wanted to see if "Chobani Plain Yoghurt 907g" was on sale anywhere this week, short of actually searching it on each individual supermarket's website, does anyone know of such a comparison website/app? I'm aware there are a couple of Android apps which list off all the Half Price specials, however these don't seem to show items which aren't on sale.
Thanks so much for the help!
