Strengths: Fast scanning workflow built for volume Cross-category: sports cards and TCGs in one app Checklist-building features for sellers Weaknesses: Pokemon is one category among many variant and set coverage is shallower than Pokemon-specialist apps Pricing depth for Pokemon (especially European Cardmarket data) is limited Best for: Sellers who handle sports cards and Pokemon and want one intake workflow
It happens, trust me
