If you were a fan of Radio Shack, this will bring back a lot of memories. I had a collection of their catalogs for several years but (like many other things) lost them in one of my moves.

We had an RS within two miles of the house--it was within bike riding distance. Had another that was 3½ miles away. It was great for picking up parts for projects I worked on, and I didn't have to bother anyone for a ride. A few of the larger purchases I made were all from their "Where Is, As Is" clearance sales. Can't say the audio components were ever that good (it didn't take me long to upgrade those to something better), but on my middle school/high school budget, they made music and at the time, that was good enough.
I am lucky now in that I live literally within walking distance of Abel Electronics (locals probably remember them under their original name of Bell Electronics in the 70s and 80s). I find they are a little pricey but, when in a pinch, I can grab something quickly. Their stock is not very deep, but they have enough to have gotten me out of a jam a few times. The only other store in our metro area is in Westland (Electronics Connection), and they have a lot more in the way of "bits and pieces" many of us are after.
I remember there were at least one or two other electronics stores on the east side back in the 70s and 80s. One of them in East Detroit (on 10 Mile Rd.) used to sell those OnTV kits in brown paper bags, like an "under the counter" purchase. (You had to know enough to ask for them.
) They ran about $50, including circuit board and case.
