Most of the relatively inexpensive wheels sold in the US are made in China. That doesn't necessarily mean they are junk but it does mean that when vendors run out of some it can take quite a while to get more. Not only do they have to be produced, which can take a while depending on how many hundreds of wheel styles the particular factory makes, then they are going to be shipped by boat, then they have to clear customs, and a week or so later they get delivered to the vendor. It takes time. And the west coast ports are still backed up from the strikes months ago. If you plan on keeping your car with those wheels on it for a LONG time you might want to pick up an extra front and an extra rear (if different) too. Aftermarket wheels often get discontinued after a few years. If you damage one you might not be able to get another.
