Best Sesame Oil Brands & Cheap Stores
As of now, I haven't found anywhere selling relatively cheap sesame oil. Hot pot restaurants feel affordable, and in my memory on a few occasions when I went out to eat, the hot pot restaurants each had small unopened jars of sesame oil that I could just take with me directly (I've never actually tried taking them away myself). The cheapest I've bought so far was probably this store's promotion; normally you'd end up paying around 8 or 9 yuan per 350ml bottle. (Mostly I use sesame oil for cold dishes and mixing into noodles.)

JD currently has a feature that distinguishes member prices from non-member prices. On top of that, there are also channel-specific prices—for example, the JD Lite app, Jingxi, and even WeChat mini programs channels can sometimes be cheaper. Additionally, when paying you can choose JD Pay, UnionPay QuickPass, digital RMB, or other methods, and stacking payment-channel discounts can bring the final price down significantly.
Also, products that have been on promotion tend to see more deals during big sales events, so you can add them to your cart and check back when you remember—if there's a deal, grab it.
PS: You generally need a JD membership. It's worth following the typical usage patterns.
