A detail that trips up a lot of mix-and-match bundle builds: a customer who wants 3 of the same flavor needs the same selector as someone mixing 3 different ones, not a separate single-SKU listing. When the single-flavor case lives inside the bundle picker instead of forcing a detour to a different page, you keep one purchase path instead of two competing ones. Small thing, but it is often the difference between a completed cart and a customer who bounces looking for the plain listing. This is exactly the kind of PDP logic our bundle app, Sleek Bundles Upsell, is built around.
