If you have a local comic store, you can make what’s called a ‘pull list’. This is basically an up-to-date list of the comics you want, and your LCS will pull them for you and put them in a folder every week, so you don’t miss out! Then you can just go in once a week (new comics come out on a wednesday), and buy them!
If you want to know what books are coming out on a weekly basis, this is the site I use! Pull lists are also a really good idea because they will ensure that you get a book that might otherwise be sold out, and everything on your list will be pre-ordered. And as we all know, pre-order numbers are what shows a company that a book is popular!
(Also some stores offer discounts based on how many books are on your list. So. Worth it!)
I hope that helped!
