Second time buying CD

This is the second time I buy a CD from the website. This time I am much more proficient than the first time, and I know how to compare prices with different parties, so I can get a better price/performance ratio. There are several album series that I didn’t know existed before. So this purchase experience is pretty good, but the delivery and overall process are slow. The seller of the CD I bought later has not shipped it for more than two weeks. This aspect needs to be improved.
