I've found that both the Borders and Barnes and Noble nearest my parents' house don't stock it at all. There is another, lesser known chain, a few towns further away which stocked several volumes, at which point I bought two of them and planned to return eventually for more when I'm home from college for a break. The Borders within walking distance of my university residence hall had a single copy each of volumes one and six (I'm planning to go back when my schedule gets less busy for the volume six, assuming it's there still), shelved in the children's department, although there were significantly more books of other Marvel Adventures titles also in stock.
