As pre-order sales for EXO's "Overdose" started, the webpage of Synnara Records crashed as fans rushed into the website.

Synnara Records began pre-order sales of EXO's mini album "Overdose" on April 15.

The Synnara Records website still exhibits a lag in their server; this is due to the massive influx of fans purchasing EXO's mini album through the website.

The mini album is sold for $13. Because Synnara Records had previously announced that they would give out free EXO posters to the first few purchasers, competition has been quite fierce.

Meanwhile, EXO returns through the "EXO COMEBACK SHOW" held in collaboration with Samsung Music on April 15, revealing their performance of "Overdose" for the first time. EXO will begin TV promotions through KBS "Music Bank" on April 18.
