Trolley Omdömen 

OK for an initial rough guide but there are too many pricing errors to be very useful. For example, they claim the price per 100g of 'Sainsbury's
Individually Wrapped Skin on ASC Scottish Salmon Fillets' is £0.24 per 100g, there are 6 portions in the pack weighing a total of 720g and the pack price is £10.50. So the actual price per 100g is £1.46. Trolley are incorrectly calculating the price of 6 portions of 720g each! I have told them about this several times but nothing has changed. There are many other errors, including the price history charts which are rubbish and wrong product links such as a link to a retailers cherry tomatoes which took me to a rear brake cylinder for a Renault Clio. I'm surprised that MSE tarnish their reputation by being involved with this site but I suppose that since the demise of the far superior Supermarket Prices website there's nothing else available.

used to be usefull site with good price comparison, up to date and email notifications of price chaanges for products on your "list". Changed to no emails, no notification, sellers added to searches which you do not want, poor search results often not including product in a major supermarket, More of time wasting marketing tool than a help with your lists of needed items. Pretty pointless and not worth the time any more. Pity

The new layout is terrible. I won't be using it again as it's too complicated.

Impossible to remove yourself from the barrage of emails, do not give these click bait hustlers your email address, next step IOC

Mistakenly registered for site, after going through convoluted process to remove account, still receiving email, flagrant breech of GDPR,

Very poor searching.
If you want to filter on ‘cheapest’ it ignores your search text and gives cheapest items of stuff you didn’t search for!
You have to try and find which category breakfast cereals might be located under as there isn’t a ‘cereal’ group.
It seems to want to find you expensive ‘niche’ products instead of everyday essentials - easier to visit the shops!

Excellent app. Updates discounted prices and alerts you when your favourite items are lower in price.

I used to check prices on my supermarket, until they gave up. I thought this might be a good replacement, but there are a few things I don't like about it. My major issue is that it takes quite a long time for them to send out the e-mail that a price has changed. I just got an alert about a price change at Waitrose that I know for a fact happened a week ago. That is just not fast enough to be of any use. There is also no way to choose only certain supermarkets for the price alerts. I am not really interested in price changes from supermarket which I can't access where I live.

This is an excellent service. Trolley allows you to keep an eye on supermarket grocery prices. Just save a list of your favourite buys and they (with your permission) will email you when the price of the item changes.
Supermarkets always boast with gusto when they REDUCE prices but when they put their prices UP, well they keep awfully quiet. In fact, silent!
Thanks to Trolley, you can beat the supermarkets at their game. Recommended.
