最爱的手机品牌出了新款、最爱的作者出了新书、最爱的电影系列出了续集……你是不是也迫不及待地自动掏腰包了？

Auto-buy refers to automatically purchase the next version or edition of something because you have liked the previous items in the series.

“自动购买”指的是由于非常喜爱某一商品系列中先前发布的产品，而自动购买下一代版本商品的行为。

例如：

"I auto-buy books they write as soon as I find out they're out," said Esguerra. "And I read them on release day."

埃斯格拉说，我一发现他们写的书出版了，就会自动买回来，而且在发售当天就开始读。
