how do you compare items , tried numerous times and nothing ,just keeps telling me to choose 2 items

[go-tazz]

The way I do it is to put them into my watch list,(via the Add to watch list at the top right of the listing).

Then go to my Watch list and tick each item box on the left of any items that I wan't to compare.

Then just click on the Compare button that will appear at the bottom of the watch list.

This gives you a basic comparison.
