I get these, cheaper than buying in store.
EDIT: For me they are $2.69/pack in Kroger vs $2.14/pack on amazon
I saw you went with a case of cans, but for future reference the packets are normally cheaper online. This brand is skyline (the fine print on the back says skytime but the address is the skyline factory in Fairfield on Thunderbird Ln.) and comes out closer to restaurant quality IMO. One packet makes about 4 cans worth of chili.
Edit: Now I see someone else suggested the same idea.
I buy these, then just follow the instructions. https://www.amazon.com/Pack-Cincinnati-Chili-Mix-packets/dp/B000E4C1OK
(This will be your reaction. "Wait. Boil the ground beef? ... BOIL IT?" Yes, my friend. Follow the instructions, you will enter heaven.)
I tried making it from scratch once but it wasn't the same. With the packets, it's exactly right. (You can also find Gold Star packets, if that's your jam.)
This is the product. The price is only a bit higher than in stores, but idk about German shipping
