```php
$productList->reduceStock(): Wagnerwagner\Merx\ProductList
```

## Return type

`Wagnerwagner\Merx\ProductList`

## Description

Called by `Merx::createOrder()` once an order is written, while
`wagnerwagner.merx.reduceStock` is true. The order exists by then, so a
product which cannot be updated is logged and skipped rather than failing
the order.

## Parent class

`Wagnerwagner\Merx\ProductList`
