Coupons and savings from http://www.r43ds.org . They are the official online store for the r4 3ds line of Nintendo 3DS flash cards, which allow you to play freeware and homebrew games and applications on the 3DS and 3DS XL systems. These include emulators for some of the best old school video game consoles and computer systems. There are also remakes of old classic games, etc...

You can use the coupon SAVE18 during checkout to save an instant 18% off your order. BUT.. where it gets a whole lot better is when you combine that 18% off coupon with their Buy 2 Get 1 free special... this way you get a free card, and the two you bough end up costing less than $35.00 for their top of the line card.
