Perhaps people who write product reviews should get into the habit of starting their review with a description of what they are reviewing, who they ordered it from, and how much they paid for it. That last bit of information is definitely very relevant if you're going to comment in your review on whether the product was good value for money.

Perhaps also put the date in the review itself and state that you do not give permission for the review to be edited.

Unfortunately, I think that some sites don't allow reviews to mention prices.

Even if the T&Cs say you give up all your rights in the review you perhaps still have a right not to be misrepresented so they shouldn't edit your review if the review is still going to be attributed or attributable to you.
