Speed stacking cup sets are available either directly from Speed Stacks or indirectly through sites such as Amazon.com and eBay.com. While SpeedStacks.com offers more selection, prices on Amazon.com and eBay.com are often lower.
SpeedStacks.com is the official site of speed stacking cups and offers shopping for individuals, group orders and instructors. In addition, it sells speed stacking sets, packages and accessories.
Amazon.com and eBay.com, on the other hand, offer more basic sets of speed stack cups in various colors. Some sets come with a mat for stacking, or a timer, whereas these accessories must be purchased separately for other speed stacking sets.
