The small retail box sold at stores like Walmart and Target, usually the cheapest full box on the shelf. Autographs are not guaranteed, but many blasters carry exclusive parallels you cannot pull from a hobby box.
Retail Box
A full box of the individual packs sold loose at big-box stores, often 24 of them. Same base set as the hobby version, with fewer or no guaranteed hits.
Cases
The factory-sealed carton a product ships in, holding a set number of boxes. A full case is the whole carton; an inner case is a smaller sealed block from inside it. Case buyers get untouched pack sequencing and a lower price per box. Some rare cards are seeded about once per case, which is what collectors mean by a case hit.
