as whenever they do - they very likely in fact use the store buffer, but they flush it and also the instruction pipeline before the load and look ahead to it to empty soon after, and also have a lock around the cacheline which they acquire as aspect o the load, and release as A part of The shop - all to ensure that the cacheline isn't going to disappear between and that nobody else can see The shop buffer contents while this is happening.
