<prompt> Human: Ive tried some websites that are out there like Krazy Koupon Lady and Google Shopping and been disappointed. Its 2017, do I really need to haunt 15 stores in person weekly to find out when grocery, pharmacy, and cleaning products are on sale? I dont buy Sunday paper long story, and it doesnt have every stores circular anyway and reading pdf circulars is pretty difficult. A circular is just a way to get you to buy stuff you werent planning on, anyway! I know what I want, please tell me when its on sale so I can stock up. I am aware there are coupon apps but most coupons are for promoting premium priced items I dont buy and generally the savings is much less than a real sale. However if there is a coupon app that alerts you when local stores have a sale on specific items I would be down for that.ETA: Wow, this is amazing! Thanks for the response. I had never heard of any of these sites. I am definitely going to give them a try.  <response>: camelcamelcamel.com for all your Amazon needs.
