My client sells hand-made clothing and gifts, and many of the products offer personalization with initials. It would be awesome to have a variation on each product with a text field for a qty instead of a radio button, and then a text field in checkout or in the product window for them to enter their initials. She charges per letter so the qty would add up the total for her. The way it seems now she would have to charge for that separately, offline.
BTW: I love the RSS feeds for the discussion board! This is a product I want to stay up on. ;)
