I have just checked coupons. The lowest price I could get is $10.99 for 800 Games Retro Handheld Game Console (in Banggood). Just check coupons out (with price alert and history). Best price?

Banggood warehouse is located in China. As you can see I didn’t find any active coupon for this product right now… Well, is it a good price anyway? This price is higher than average price ($10.57) for this item.
