We get like 4-5x our exec. membership fee back in rewards cost every year - and I stopped buying tires/car batteries there (takes too long / quality no longer as good) and usually go to best buy for electronics (their return policy is no longer as good, and they often stock sub-par models, etc). Even with that, Costo is essentially paying us to save money.

Yeah, with TVs, Costcos in our area only stock one tier of Samsung models, but "worse" they're recently the 2-3 year old model that has already been superseded. And while the markup is minimal, you're still paying retail for a 3 year old model. Shades of Apple selling the Mac Pro 2019 (cheese grater) with a 4 year old Xeon processor at "full Apple" prices (I almost said full retail, but full Apple is a bit more), and with RAM prices from 4 years prior, too.
