Start from the beginning.
1 - A few days later in Power Lad's kitchen. Power Lad sits at the table, looking at the package on the table with excitement.
CAPTION: 3 to 5 business days later...
POWER LAD: I can't believe it's already here!
2 - Power Lad starts opening the package. He looks confused at what he's seeing.
POWER LAD: Wait...
3 - On the book in Power Lad's hands. Unlike the one in the commercial, this book is titled "Heroes are Zeroes" with "On being the worst villain you can be" as the subtitle. Maybe have a stereotypical Snidely Whiplash-esque figure on the cover or something similar. There could potentially still be some wrapping on the book as he pauses to process what he's seeing.
POWER LAD (off-panel): ...this isn't right.
4 - On Power Lad again. He looks to his left warily.
5 - Repeat, but Power Lad now looks to his right.
6 - Power Lad is reading the book intently.
