If the order price is cheap, it is mainly because of the difference in account level:

1. Diamond member price. If the purchase amount is large and the membership level reaches diamond level, some products are subject to diamond member special prices. For example, I bought an HP ink cartridge once, and the large set of color + black was only 209, while a single box of color for non-diamond members cost 200+

2. Member Plus price. The annual fee is 149, and the products are updated every Friday. Those products enjoy the Plus member price. For example, I bought a Boss perfume + shower gel set, the original price was 799, and Plus members only needed 299.
