When I was a kid, we use to be able to order books from this little magazine. The little magazines use to look like the image below. You’d have a few pages to look over the books they offered during that period, along with the cost of each book. Then there was a little order form on the back page for you to turn it what you want along with your money to pay for it. There were a few random things that they sold in these little magazines, like games or posters and stuff like that. But it was mostly books and they were usually catered to readers depending on your reading level (they were all suitable for kids).
Does anyone else remember having this when you were in grade school? If so, how much do you think you spent back then? Do you remember what you bought?
