Aliexpress.com, eBay, and DHgate.com all have Pokemon EX cards for sale in bulk for cheaper than can be found in stores. They show up in lots anywhere from two to 60 cards per sale.
Prices range from lot to lot, and usually are comprised of random cards. However, if the customer is looking for quantity at a cheaper price, this is a good option. The EX cards are more stylized and come with a full-art print, making them look different from normal Pokemon trading cards. They were first introduced in the Next Destinies expansion and most are legal in tournament play.
