I bet this is related to another quirk, where &quot;sort by price&quot; doesn&#x27;t really result in things being in the expected order.<p>I suspect (because I have a similar challenge in our own ecommerce system) that the model underlying the representation of products has at least one additional layer of specificity, that&#x27;s not directly revealed to the user. Consider that you&#x27;re looking at Products, but what they&#x27;re really manipulating are products <i>as sourced from a particular supplier</i>.<p>Each of those &quot;supplier-items&quot; has its own price (because with Amazon marketplace, the supplier gets to set their own), as well as its own potential shipping destinations.<p>When you project that into search results as a list of <i>Products</i>, what you wind up with is a list of &quot;Products for which there&#x27;s at least one supplier willing to ship to Iceland&quot;. And the sorting is something like &quot;order by lowest price offered by all suppliers&quot;. When you click on that product to go to Product Details, and then just click &quot;Add to Cart&quot;, they&#x27;ve lost the thread of &quot;I need to select a supplier of this product that will ship to Iceland&quot;.
