Quickly off the top of my head,tennis shoes. In the 70's and 80's, shoes were much more expensive, now we found slave labor, I buy a set of sneakers for 30 dollars at cabelas by newbalance and pretty comfortable. And of course clothes. When I used to buy business casual in 1990, a set of docker cost 40-50 dollars. Now, I find them easily for 25 a pop.

Lastly, my company, used to sell 2.5GHz data modules for 25K, now they moved most manufactuing to thailand, we seel data modules for 5K and are 4 times the speed.

These are just quick things on the top of my head.
