Life is Strange: Before the Storm (Limited Edition) - $15.xx from Amazon
Includes (the game + bonus episode "Farewell" as DLC voucher)
+ Before the Storm soundtrack
+ Before the Storm artbook
I've been watching this gradually drop from ~$20 for the last few days. It bottomed out at ~$15, and is starting to rise again in price, so get it while the deal Is good. Cheaper than the standard edition currently. There are some used copies from Amazon Warehouse for a few dollars cheaper, but I highly recommend getting the new one to ensure an unused code for the bonus episode "Farewell".
