As someone who works in the retail industry, I am pretty familiar with how these situations work. Usually, the (original) manufacturer will issue the recall through the retailer (in this case metadot, directly, or some other third party retailer). The OEM replaces the product at their expense, thus, metadot should not take (much of) a hit financially. Any shipping costs, etc., will (should) be covered by the OEM. The retailer might pay for shipping from the consumer back to the retailer, and the OEM, in turn, will reimburse the retailer. Many times, we also fine our OEMs in these cases as well. I believe this is to collect some kind of "punative damages" for megatively impacting our brand name. This scenario was very similar to how the product recalls were handled when China provided tainted wheat for products like dog food. The company that provided the wheat covered all expenses and was fined quite heavily, among other things.
