I never used to believe stores would blatantly jack up the price of products during eBay sales and all, but seems as ShoppingExpress just does this:
Their website has the 3060 for $889
Meanwhile ebay for $1,075.
I understand ebay charges fees, but these fees are due to ebay attracting alot more traffic than your noirmal website.
It's like clothing store in Westfield complaining why his store pays $5,000 / week rent compared to the guy outside on the plaza.
Having said that, even if we were to offset the 10-11% fees, then the product should be 889+10% = $977 on ebay,
"Price gouging occurs when a seller increases the prices of goods, services, or commodities to a level much higher than is considered reasonable or fair. Usually, this event occurs after a demand or supply shock"
So is $889 fair? I dont know what your problem is.
