Category research
Start where comparison is fair.
A shoe, a jacket and a watch need different evidence. Category-first research prevents a spreadsheet from becoming a random pile of tabs.
Shoes
Profile, sole, heel, size notes and material photos.
Hoodies
Measurements, fabric, print placement and package weight.
T-Shirts
Fit, fabric, print and source-page consistency.
Jackets
Lining, dimensions, material, closures and weight.
Pants
Waist, inseam, fabric and size-chart evidence.
Hats
Measurements, shape and close-up construction photos.
Accessories
Dimensions, hardware and source relevance.
Jerseys
Material, badges, fit and print detail.
Electronics
Specification, compatibility, condition and shipping restrictions.
Other stuff
Use the strictest relevant category checks first.
Each card opens the matching FindSpreadsheet search. The guide does not sell, verify or ship products.
