I don't know if ebay team uses google or not but many products on ebay are much higher than on other popular sites.Now dont excuse that ebay is very reliable and other are making fools.Some are global and india leader and very respected and trusted site.Many sites have enough range of products with much lesser prices.
Just search the price of any mobile viz. Moto G,Micromax cnavas series,Lumia series,kitchenware etc. the prices are 200-5000 higher.Even local vendors are selling cheap.I searched a mobile available @ 9000 but few sellers on ebay selling @ 14000.Are they nuts.
The crux of above writing is why a global company like ebay cant offer competitive price wrt other e-commerce sites.
