Reddit – Dive into anything

I purchase my books online as the shops here sell them at maximum retail price and there are always discounts on Amazon in my country. The Collins Classics are available for dirt cheap price here and it’s tempting. Have any of you read the Collins Classics edition of Emma, Sherlock Holmes, or Journey to the center of earth? Since it is online, I cannot physically check the font and size of the book, but it feels the price is definitely worth the amount of pages those books have. Or should I spend more bucks and buy Penguin Classics for better readability?

PS: Penguin classics cost almost twice as Collins Classics.
