GameLink said the sale is a way to share its success and show loyalty to its customers.
"To thank GameLink's millions of customers worldwide - and, hopefully, win a few new ones, too - we're having a fantastic three-day sale," said Jeff Dillon, director of business development. "Our catalog of DVDs and toys is one of the world's largest, and for a few days this week, every item is on sale."
The discount will apply to thousands of in-stock items, including adult DVDs, sex toys and apparel.
Sale items will include products from top studios like Vivid, Club Jenna, Digital Playground and Evil Angel, whose premium titles rarely are offered at discounted prices.
