Hmm, I didn't notice that. It's very strange (and probably not legal under the US Magnuson-Moss Warranty Act). But
it really makes no difference (to me) because Newegg will
replace a defective unit for a new one for 1 year.
I guess I'm still concerned because Newegg's mail-in rebate policy says products offering mail-in rebates are not returnable once the rebates have been filed and only the product manufacturer can replace any defective item missing the UPC code.
