Clicking the "all to cart" button takes you to a page reading "bonus special
offer". To get past that page, you have to click either "yes, change my
order" or "no thanks, proceed to checkout with my original order". Seems
pretty clear to me, however, one might be confused if he had not read the
options and tried to actually place the order.

However, in most cases, the add-on is very clearly marked
and is a selectable option, not the default. I haven't verified the OP's
claims vis a vis the cited web site; however, if you read his description,
the add-on is the prominent display and the purchaser's initial intent is
a
small, hidden option.
