Rakuten has daily deals available with some nice discounts, after you apply a promo code. Included in today’s deals there’s also a $50 Microsoft Xbox Live eGift Card for $40. You need to use promo code SAMSUNG20, limit 1.
Rakuten also has their own rewards, Rakuten Super Points. Members automatically get 1% back in points on every purchase, and you can use the points to purchase gift cards as well. So this could be a good use of the points you might have received from their last sale
