Regular Incorrect Prices

Prices are incorrect on a lot of items. I check them religiously before shopping & often find they aren't anywhere near what Trolley says. For example;- Coffee prices are often miscorrectly stated. As of now, you state 3 shops having coffee (freeze dried or similar) at £2.45 for 200g but these are actually £2.69 and have been for well over a month. This happens on other items which can be disappointing when I schedule my shops & find incorrect prices resulting in having to return to other supermarkets or shop on another day. Maybe the data you are using isn't updated very often? An addition to the site would be to let users report prices & these be used if repeatedly reported the same.
