Say an eBay seller advertises product (A) for $x dollars.
eBay says to seller, we'll have a 20% off special on your store, we cover 10% you cover 10%. Now even tho the consumer gets a good deal, the sellers cost has increased, could this be the reason for some cases of price jacking?.
Course it is, and I've mentioned it before. It common-sense that it's the case.
Ebay sellers won't disclose it because they're behind NDAs
