Question 1

What does Grand Total cost?

Accepted Answer

Nothing, and there is no account. We earn commission on some of the links that lead on to a shop. It does not change the order: that is decided by the total price delivered and by nothing else.

Question 2

Why is the cheapest price per item not the cheapest basket?

Accepted Answer

Because shipping is charged per order and not per item. Follow the lowest price on five items and you end up at five shops paying shipping five times — and that can easily come to more than gathering the whole list at one shop, where the shipping is free.

Question 3

What do you measure the saving against?

Accepted Answer

Against finishing the whole purchase at the shop you are standing in. Not against the cheapest single shop and not against buying item by item, because both would be a yardstick we had chosen ourselves.

Question 4

Which browsers does the extension work in?

Accepted Answer

Chrome and Edge run it as it is, and the Firefox and Safari editions build with one command. None of them has been published in a browser store yet, and until then the list can be worked out on the site without installing anything.

Question 5

What do you keep about me?

Accepted Answer

There is no account and no e-mail. The list sits at an address that cannot be guessed, and the extension has no access to a shop until you switch that shop on yourself.

What do you need to buy?
