Hey so I've been seeing lots of ads for bookish subscription boxes lately and am tempted to subscribe to one. I've also seen one-off book boxes, some of which are purely books and some have extras included, usually stationary or tea. If anyone on here has bought any could you let me know whether it's better to buy book boxes that are just books? Or if you've bought ones with extras, have you actually used any of the products added in? I really don't want to buy useless junk for the sake of it. Thanks!
