Questions people ask about comparing prices on iHerb

Does iHerb show the price per 100 g or per gram?

On some product pages, yes — but not on listing pages, and the unit changes: per 100 g, per kilogram, per count or per serving, depending on the product and the country storefront. Two products side by side on the same page often cannot be compared directly. getillumi.net calculates a consistent price per weight for every product on the page and sorts by it.

Why do per-serving prices not compare between brands?

A serving is defined by the brand, not by any standard. One protein powder calls a 31 g scoop a serving, another calls 40 g a serving. The price per serving then says more about the brand's packaging choice than about value. Price per gram, or price per gram of protein, removes that difference.

How do I compare protein powders by price per gram of protein?

Divide the price by the total protein in the tub — grams per serving multiplied by servings per container. It is simple arithmetic, and unbearably slow across a page of twenty products. That is the calculation this extension automates, reading protein content and package weight from each product and ranking the page by protein per unit of currency.

Why does a multipack look cheaper per gram than it really is?

Because the product name states the weight of one unit, not the package. “12 Bars, 1.4 oz (40 g) Each” is 480 g of product, but read carelessly it looks like 40 g — twelve times lighter, which ruins any price-per-weight comparison. getillumi.net reads the unit count and cross-checks it against the delivery weight, so the package is compared at its real size.

Can I sort iHerb results by sugar or sodium?

Not on iHerb itself. This extension reads the supplement or nutrition panel from every product on the listing you are viewing and lets you sort by sugar, sodium, protein ratios, servings per container and several other measures.

Is there a free tool for finding the best-value size?

Yes — this one. No account, no payment. It checks the other sizes and flavours of each product on the page and can switch every product to whichever variant costs least per gram, so you can see the page at its best available value.

Does the extension collect my data?

No. It reads the iHerb page you are already looking at and does the arithmetic in your browser. There is no account and no server of its own, and nothing about your browsing is sent anywhere. The only thing it stores is a local cache of product sizes, kept for a day so repeat visits load faster.
