A trip to Kmart and Toys "R" Us could save you cash for maximizing your 3DS library.
Toys "R" Us is offering a buy one, get one half off deal to all customers who purchase Nintendo 3DS games at the retailer when 3DS launches this Sunday. With most 3DS games costing $39.99 this will cut the cost of two games from $80 to $60.
Kmart is also offering $25 towards the purchase of one 3DS game to all customers who purchase a 3DS from them this Sunday.
An adventurous consumer could save $45 by buying their 3DS and one game at Kmart, and then buying two others at Toys R Us.
