The 7-Eleven two blocks from my house was the final depository of every 20 (then 25, then 30) cents I got my hands on between the age of 11 and 15. If the pickings on the spinner rack were slim, I might divert some funds towards a Slurpee (in a Superhero cup) or a Mad Magazine.
Nothing beat the intoxicating smell of testors glue. K-Mart had a huge model isle back the the early 70’s. Comics books were purchased in a spinning rack at our local five and dime store called Catrabone Variety in Wesleyville PA which also had a respectable model selection.
Oh yeah, I remember that. I loved the smell too. Then they took out some key ingredient, toluene I think, just because it caused cancer or some silly reason like that. then the glue not only didn’t smell as good, it was no good at bonding the plastic together.
Our Giant grocery store had the spinning racks, and Mom would always get me a comic book when we went (usually Metal Men). When I was a little older, there was no place like George’s Confectionary in downtown Bristol, VA. They not only had comic books; they also had Playboy and Penthouse. Better yet, the guy at the counter wouldn’t say, “this ain’t a library.”
When I was in grade school (mid 60s to early 70s) it was the tail end of the days when trash bags weren’t a thing yet and your trash barrels were a couple of 50 gallon steel drums. There was a house on the way to school where every so often (at least 2-3 times a month) there would be a stack of 5-6 DC comics that had just been thrown out. That was where I got all my comics when I was a kid.
Wish’s Drugs was near where I lived and was my usual destination for comic books. But if I was looking for something a little off the beaten path, or if I needed to hunt down a back issue or something, The Great Escape was the place to go. I really ought to pay The Great Escape a visit next time I head back to see the folks. Heck of a place.
My place for model kits in the 60’s and 70’s was the B&I in Tacoma. They had a huge hobby section in what was a huge store. I use to build stock car racing kits and they carried them all. Plus they had decals for lots of the cars that did not come in kits. Plus I would go see Ivan the gorilla while I was there. By the time I quit building model stock cars I had over 120 assembled cars and 50 unassembled kits. Sold the entire lot to a guy from Texas.
There were three pharmacies.
Two in Pewaukee, one in Waukesha.
One of the phramacies in Pewaukee sold models.
For models, the place for me was mail order from Auto World. The local stores had nothing, one or two random kits. K-mart and Copps in Oshkosh were the best places I had actual access to.
But Auto World! They had everything. or not, but they’d give you a voucher. Not just models but slot car parts! gears for 0.05! Individual springs, pickups, wheels, and they’d come cut from the little blister packs.
Speaking of, when I moved to LA in 1985 I hit every hobby store I could find. I figured if anybody had unsold stuff clogging the shelves, it would be in LA. I used my old information that came with my race sets - they would list local hobby shops that supported Aurora. Some were still in business in 1985. Found the mother lode at Palisades Hobby - Aurora T-jet track in the yellow and blue boxes, and parts in those same blister packs, still there, still unopened, still ready to buy! I found an unsold T-jet race set (Sand Van, with the tan track) unsold, still labeled and sold at the 1969 price! I bought everything he had.
I ordered a bunch of slot car stuff, and other model car stuff, from Auto World back in the '70s, too. Good memories. 
By the way, they’re still around! https://www.autoworldstore.com/
Comics? The spinner rack (good description) at the Rexall pharmacy easy walking difference one traffic light away. Model kits? The 5 and 10. When I started reading comics there were still echos of complaints about the price going from 10 to 12 cents. When I was 9 1/2, my dad bought a news store from his cousin and I didn’t have to buy comics anymore, I just censored them.
Shinders newsstand on Hennepin Avenue in downtowh Minneapolis for comics.
Woodcraft hobby shop on West Lake Street in Minneapolis for models. Ring’s hobby shop on South Cedar Avenue was pretty good too.
