Yeah, when I was a kid, it wasnt just cash that was limited, the comics were very limited too, here in the UK we didnt have many comic shops and the few we did have didnt have access to a lot of stuff as it wasnt always distributed, so you just had to grab anything you could, the grade wasnt even an issue for me, thats why my collection is all over the place condition wise.
There was a short lived bookshop near me that sold comics based on age
1 x 1950s comic = £1.00
3 x 1960s comics = £1.00
5 x 1970s comics = £1.00
I pretty much always bought 5 x 1970s comics with my hard earned £1.00
