Amazon announced today that one of the best perks of Amazon Prime, a 20 percent discount on video game pre-orders, is ending next week. Instead, Prime members who pre-order an eligible game will receive a $10 promotional credit to their Amazon account “up to 35 days after a qualifying purchase.”

The new policy takes effect on Aug. 28, which means Prime members have one week to pre-order 2018 (and some early 2019) releases before the 20 percent discount goes away. Thankfully, Amazon lists new games practically as soon as they’re announced, so even some games without firm release dates are available for pre-order.
