Head to head

300 seller comparisons

Each one sets two sellers against each other on what the checkout actually bills over a calendar month, rather than on the figure each advertises. Every pair here differs on at least three of five facts — price, billing cycle, dose basis, compulsory fee, published coverage.

43 where the cheaper-looking one is the dearer one

The seller advertising the lower figure is not the seller that costs less over a calendar month. That reversal is the reason this index exists, so these lead.
