what? Gateway is $100 and R4i3DS is roughly $66? where did you see? it is so impossible. which one do you want to buy? the price in this website is very fair. but i cant link to you. you can search prima-module.com in googel. good luck.
Its a local store here in the Philippines. Well, I already ordered online via nds-card.com and its also amost $100. 80 for the gateway and 18 for ems shipping. Hoping our customs won't tax me. Nds-card said they will just declare $10 as the price for the item.
