The feeder Sheila cannot remember buying

Look something up, see straight through the results that were paid to be at the top, work out what it truly costs to get to the door, and keep the page so you never look for it twice.

Every errand in this course came down to the same two habits: start where you chose to start, and read one page further than you meant to.

Here is a practice computer and a small piece of shopping with a fact attached to it — somebody has already bought this exact thing and told you what she paid. Nothing on the screen will tell you which result to press, and the first two will be doing their best.

What to remember

Try this

Look up something you have bought lately and find where its delivery cost is written. On nearly every store it is on a page of its own — Delivery, or Shipping, or Shipping and returns — and it is the whole difference between two prices that looked the same.
