Seems like you (parser) gets doppler skins phases/gems csfloat prices with filter “Best deals” instead of “Lowest price” for some items. Sometimes its wrong as csfloat adds significant overpay for float especially on top1-10 items, leading to prices 10–40% above market value.
Examples: 1) Survival Knife | Doppler - Phase 2 (Factory New) on website shows that on csfloat is costs 550$, however lowest price ~400$, first best deal - 550$ due to #2 float overpay (fixed by low float skin owner price increased so now not 1st best deal)
2) M9 Bayonet | Doppler - Phase 3 (Factory New) shows 2130.00$ (1 stock) on pricempire, on csfloat lowest price ~1930$, first best deal - 2130$ (0.001 float, 0.4% discount calculated by csfloat but still too high)
3) Paracord Knife | Doppler - Black Pearl (Factory New) shows 1100$ (1 stock) on pricempire, on csfloat lowest - 1080$, first best deal - 1100$ (0.01 float, 0.2% discount)
Fix: adding “&sort_by=lowest_price” to http query for authorized requests i guess
seems like this problem appear only with some dopplers phases
