目前的戴尔官网的价格为319.99$。
首先注册Rakuten账号以获取15%的返现，记得点击链接从Rakuten进入Dell官网之后再搜索显示器型号加入购物车，以及提前登录好个人账号。
加入购物车后，使用该链接以获取优惠券(不需要工作或者学生邮箱，只需要一个没有注册过Dell账号的新邮箱即可，优惠码会发送到邮箱)
下单之前在My account中找到Dell rewards，点击Game进行游戏以获取积分,每1000积分可在下次购买中节省10$。（有攻略说第一个游戏选择“business owner”这个选项可以获得更多的积分）
最后下单大概可以做到240$税前，至此，你可以省下80$购买一个具有3年保修的2k144hz IPS显示屏。黑五的返现需要等待一段时间，订单完成后还会有一些Dell Rewards 可供下次购买使用。如果有小伙伴购买成功可以评论一下节省了多少钱。
