I used to shop at HT at the last place I lived. It was always crazy seeing all of those discounts pop up. I don't know if I was actually saving money over the other stores nearby but it certainly felt like it. Honestly, I like shopping at Lidl now. My grocery bill always feels much cheaper. I don't get much savings using my phone number, I think they want you to clip coupons on the app but I still walk out paying less than I would elsewhere. A large portion of the stuff at Lidl are not major brands, I suspect they are the companies that produce white label products for store brands.
