The market is full of operators offering branded stock they don’t actually hold, listings that don’t match what arrives, and suppliers who have one good line then nothing worth buying for months afterwards.
If you’re a retailer filling shelf space, you can’t plan your stock room around a supplier who might or might not have something next week. If you’re selling online, you can’t list products you’re not certain will arrive in the condition described. And if you’re buying in volume, every bad parcel - damaged goods, miscounted cases, packaging that’s been sat in a warehouse for two years - costs you time, margin, and customer trust.
