Fyi Tayda is located in Thailand which is still a developing country.
Apart from maybe the huge different at the shipping charges like those cut throat Fedex/UPS/DHL vs Thai's government backed postal office charges, I believe Tayda's employees don't have lots of benefits compared to say like Digikey does, just watch below video for your self, they got best around pension plan, best medical cover ... and so on.
So there is no contest here about the operating cost, hence the merchandise's high price mark-up.
