What is added or changed in each character?
Dark red marks the deciding detail
Why the difference is easy to miss
头 and 买 and 卖 and 读 and 实 share an outline that is easy to read too quickly.
Treat 头 as the core: 买 = 乛 + 头; 卖 = 十 + 买; 实 = 宀 + 头; 读 = 讠 + 卖. At a glance, that shared shape can make the added component around the shared 头/买/卖 core for each character easy to overlook.
Check the shape first, then confirm with the word.
If the surrounding word/meaning conflicts with the character you first recognized, re-check simplified shape.
