This is not the right place for your question, Guest. This is a social networking site and not a plant sales area. I guess that you have seen the bulbs in the 'Garden Center' part of the site which contains links to various on-line sales organisations. You should ask them directly.
As a general rule I would expect all bulbs being sold to the public like this to be of flowering size and to flower in the first season. I would complain if they did not.
