A:AnswerHello Josh,
We would like to inform you that this is its own blender. The model number is BL682; however, the attachments for the BL682 will fit the BL681A.
We hope this information helps.

A:AnswerEvery store is different but the one I went had at least 3 on the sales floor. The reason I'm thinkimy they don't keep a lot in stock is ...they have so many varieties.
