Escape from Tarkov
Loot Value
Escape from Tarkov bags fill with trash if you loot with your eyes instead of with slots. Take items that sell or craft. Drop the fifth screwdriver.
Slots per currency
A 1x1 that sells high beats a 2x2 souvenir. Learn a short list for each map. Do not invent value in a raid.
Quest items override flea value. If you still need the item, it is not junk.
Containers change the math
A docs case or a lucky scav junkbox is a different game. Until you have one, be cruel to your own inventory.
Tech vs intel vs meds
Interchange is not Woods. Loot the map you spawned on. Walking across the whole region for a fantasy GPU is how you die overweight.
