I will appreciate if someone hint me the way to sell “out of stock” configurable products. What and where should I change to allow selling “out of stock” configurable products?
I read lots of posts here on the forum but haven’t got a clear answer. I also found some extensions for this purpose (but they are not free and I would not like to pay for that).
I guess the suitable solution for you will be to set for your configurable products, the option Manage stock to “No”.
There is the application called Store Manager for Magento. It has many built-in and custom filters. Using it you can filter your products (select all configurable products) and then choose option Multi-Editior, that is built-in Store Manager. Using it you will be able in bulk change product information in 2 clicks.
