A "retail curve" refers to the limited options that are commonly sold in stores. For example the P88 (AKA the "Kane"), or the P92 (AKA the "Backstrom" or the "Sakic"). Like we mentioned in the pro curve section above, those 3 players never actually used that curve that is named after them in stores. The big brands will sign players to endorsement deals and then assign one of their stock "retail" curve options to each player. For example look at the naming history of the P92, it was the "Backstrom" and then the "Ovechkin" but both of those players use custom "pro curves" that are completely different from the P92.
