You are buying it from dailysteals through ebay. So the odds of getting fraudulent memory is low.
I'd be more concerned, however, by the "new other." It's probably used, refurbished, or excess inventory. The price seems high for a used item and dailysteals has a shady reputation for pawning off as new items that are actually refurbished or used.
Dailysteal is shady, period. They sell used items as new, broken items as functional, and fakes as real. This deal is no better than buying a flash card from any other random eBay seller.
