|---|---|---|---|---|
| Metformin 1000mg (20 Tabs) | 1000 mg | £12 | £0.01 per mg | in stock |

Comparing on cost per milligram
Cost per milligram is calculated from the strength printed on the listing. Where a listing states no strength the column is left blank rather than estimated. Cost per milligram is the figure that survives a change of presentation, which is why it is the one to compare.
Strengths listed
Everything in this range is supplied at 1000 mg, so listings differ on presentation and price rather than on strength.
What moves the price
Price across a range moves on three things: the strength on the listing, the presentation it comes in, and whether the item is held in the UK or has to be imported.
