Yeah, Target's DPCI system lumps everything Legends under one number, everything Vintage a number, CW, etc., etc.
Pretty much every other retailer uses a different system that has every individual SKU in their system, but it's how WM for instance runs into issues where an individual figure (or more) from a wave can't be sold because their SKU's aren't in the system while others are... Lumping it all together is beneficial, but at the same time you can also manipulate it by returning stuff you don't want on the same receipt which can screw with stock/inventory issues obviously.
