As far as knowing what you want when you walk in the door, I think that you will get skewed results on HNI.
RJ, I tend to agree with this statement. But, there are literally thousands of people on this forum each and every day that aren't members and do not post. I personally feel like, especially the younger crowd, there is an aweful lot of "comparison shopping" and research being done before they step into the shop. I've seen an increase in this in just the last year and feel like this is an extremely credible way to get a pulse for what people want and are doing.
And in having these questions answered, I can get a pulse for what people are wanting, and we can stock accordingly. There are SOOO many accessories out there, it is impossible to stock everything, unless you're bass pro or cabelas. Which we certainly are not. And, knowing whether folks will wait for what they want or not will help determine how much, and WHAT, to stock.
