Where’s the best spot near Chicago to buy quality fireworks before New Year’s?

Every year I end up driving to random stores across the border, and it’s always a hit or miss. Some places are overpriced, some barely have anything left a week before the 4th or New Year’s. This time, I’d rather plan it properly and get a good deal.
I’ve seen a few people mention online options that ship to Illinois or just over the Indiana line anyone have actual experience with those? Looking for quality stuff, not just fountains and sparklers. Ideally something that can be delivered or picked up close to Chicago.
