I normally disagree with this type of comment, but based on the actual survey they refer to [1], you appear to be correct. The most probable way I see that they've come to this number is by using the other side of "24% of consumers never use online reviews". The rest of the data is "27% of consumers regularly use online reviews" with the remaining 49% checking occasionally.

The way the statement is worded, I feel that many would read it as "A recent survey found that 76 percent of consumers regularly check online reviews before buying" even if that's not how it's written. A better statement would make the breakdown of regular vs. occasional checkers clear.

That said, single word comments don't add much to the conversation. As stated, and if the survey is to be believed, the line is factually correct even if it is misleading. I'm not sure if "bullshit" refers to how you interpreted the statement or the results of the survey. Without clarifying your objection, though, it will likely be ignored by most.
