I am currently building a site and I am looking to give customers a free item of clothing with every purchase. I am using this extension below to try to achieve this:
http://www.magentocommerce.com/magento-connect/gift-rules-5571.html
When the customer orders anything from the site they should see a free pair of slippers appear in the basket. However the issue is that everyone needs to select the shoe size so they get the right ones.
I tried creating a product that had a required custom field of "Size" but when I added the rule to put that item as a free gift the system crashed and this was because the item was added with a required field that was empty.
Then I made that field not required and it worked thinking that the customer could edit the product in the basket and pick a different size, however when they do that a new pair of slippers is added to the cart at full price and the one set as gift isn't updated.
Has anyone got any ideas on how I can achieve this using either the extension I have installed or by another way?
Thanks
