I think the fact that our tds ship internationally which means their business is riskier pushes their prices up. What happens when customs takes your watch? You get another one. These guys sell mainly to China and the risk of anything going wrong is minimal.
So basically if one out of every 10 watches sold by tds goes missing or something goes wrong with, they need to push up the price on all the other watches by 10%
And yeah there's a big profit margin. We know that. Sead is selling the 512 for around $70 cheaper than Josh for instance.
But good find op I always did wonder how much they added on top because I know the Chinese are fond of their reps like us
