The percentages shown are against each retailer’s own “was” price. Open any deal to see its price history, and judge the saving against what the product has actually sold for rather than the headline figure.

What to check: Compare the cost per 100g of protein. Whey concentrate is cheaper and whey isolate is higher in protein with less lactose, so choose according to budget and digestion.

You buy from the retailer, not from us, so confirm the size, stock and returns terms on their site before you pay.
