The only way to know how much cheaper is to look on Ali Express. That’s how I wound up there.
I don’t spend mental energy dealing with Amazon’s dark patterns and terrible search that is flooded with sponsored links for something I did not search for…Ali Express search is not great, but it is not adversarial.
But because it works for me doesn’t mean it works for you.
For example, I need a 74hc245 for a repair I am working on. I just bought 10 chips and three 3m USB C/C cables and 50 velcro wire wraps for $10.61 including shipping.
The best price Amazon showed me for the chips was $9.99. I got $14.99 for two cables. And $6.99 for 60 wire wraps.
As for shipping - if it's not urgent, I just put it in my Wishlist until I accumulate items beyond the free shipping threshold.
