Import used to write no price at all — "import is not pricing, the merchant sets
|
|
it". Right about who decides, wrong about what a shopper sees in between: the
|
|
product went live at ₹0, which on a phone reads as free rather than as unpriced.
|
|
A product uploaded by sheet carried its price and showed it; the same product
|
|
imported from the catalogue showed nothing.
|
|
|
|
The catalogue quotes a range as a string, so it has to be read rather than cast.
