Ya no that's not how this works. Retailers sign deals that allows them to get the product early so that on launch they have them, and in exchange they can't sell until launch day. There's a LOT of negotiation and deals between retailers and suppliers, it ain't just a "buy and sell" situation as you seem to understand.
i mean the ppl who buy them FROM newegg...aka end user who they (newegg) is trying tell em not to post about em.
they have no power over what ppl do when they sell them to ppl early.
thats like buying a car early and dealer saying "yo you cant drive it until [date]"
they can say all they want but owner doesnt have any legal reason to listen.
unlike ppl like who sign do not disclose to get early samples average joe who bough those on newegg never signed a thing.
Newegg likely broke something to sell em early. Thats on them thoguh not buyers.
