We grouped listings whose titles matched word for word but had different ASINs (Amazon's product IDs), then compared the lowest and highest price in each group. A price gap here is between listings, not between sellers of one listing. Full method in the \u003Ca href=\"/blogs/amazon-uk-marketplace-report-2026\">Amazon UK Marketplace Report 2026\u003C/a>.

So can a single bottle of shampoo and a multipack. Two listings can carry the same title, word for word, and still disagree about how many bottles are in the box.

When the unit prices land close together, the gap was the pack.\u003C/li>\n\u003Cli>Read the end of the title.

They help each listing rank for the same search, but they also invite a shopper to compare a single item with a multipack and wonder why one is so dear.

A report built on title matching will flag "price gaps" that are really pack sizes, and someone will spend a morning chasing them. A report that normalises to a unit price will show which gaps are worth a call.
