Sometimes a deal looks great at first glance, but then I notice the same item being sold for much less somewhere else. I am trying to build a better habit of comparing prices so I do not waste money on impulse purchases.

Lately, I have been checking price history, comparing different shops manually, and using a couple of tools. One of the things I tried recently is a tool called Redcart, which shows factory-level pricing for some items. It helped me realize how big the price gaps can sometimes be, but I still cross-check reviews and store apps because the cheapest option is not always the best.

How do you all verify if a price is truly fair? Do you rely on price history, comparison tools, store apps, or something else?
