Could you help me translate these comments about Messi leaving Barcelona? There's this news. I'm reading comments, not quite understanding what the authors meant. I hope this kind of grouped questions are OK on Chinese Stack Exchange. I don't want to exaggerate, so I'll only put a handful of them. I'll gladly accept answers which respond only partially to these.

促销巨惠，等你来 - I don't know how to translate this.
这波反转我吐了 - I think it's something like &quot;I've had enough of this storm of ever-changing information&quot;?
影帝 梅西 - 帝 is emperor, but this 影? What's 影帝? Google Translate says it means &quot;Actor&quot;, so does the author mean that Messi fakes fouls?
整理了一些（p.s，p.r）存货，都是干货 - I don't know how to translate it.
讲的通俗易懂，都学完了，有想学习的吗？ - shouldn't 的 be 得? I know 通俗易懂 means &quot;easy to understand&quot;, but I don't understand this sentence.
再发挥一下价值，分享给有缘人。 - the first part probably means &quot;Once again he's reminding his value&quot;, but what's after comma is incomprehensible for me.
需要的留下邮箱，发给你 - I have no idea what it means.

Thank you in advance!
促销巨惠，等你来 - great discount, waiting for you.
这波反转我吐了 - The dramatic change makes me feel sick.
影帝 梅西 - Messi should win Oscar for Best Actor.
整理了一些（p.s，p.r）存货，都是干货 - Prepared some info I reserved before. They are all &quot;information without beating around the bush&quot;
讲的通俗易懂，都学完了，有想学习的吗？ - Speak in plain language. Have you learned all of it? What else do you want to learn? (or maybe &quot;Anyone what to learn?&quot;)
再发挥一下价值，分享给有缘人。 - Make use of its surplus value again. Share it with whoever is lucky.
需要的留下邮箱，发给你 - Leave your email here, I will send it to you.
