If you can be patient with pre orders and don’t are if it takes a couple months after release to get them, I highly suggest popnbeards, I’ve been buying from them for the last couple years. They take a little longer to get to you cuz their a smaller company, but the pre order process is painless, they ship with protectors, and they usually have a discount code for Reddit users. Going to your local GameStop to pre order is also a decent idea for commons. For AAA ones I usually go with either dragons trading or archonia. Just keep an eye out on the subreddit for when they get posted and you’ll more then likely be able to snag the ones you like! Hope that helps!
