I've been here since the early days of 3e. I've never, EVER, heard of an in-store conversion guide. I was shopping at three different stores at the time, and I never, ever saw such an in-store conversion guide. I am not saying you didn't get one. However, I am saying that either 1) your store printed them for their customers and were not actually "sent" them from WOTC, or 2) you encountered a relatively rare in-store conversion guide that many people never saw or heard about.
Nope- its an actual WotC product, nice & slick, and as I just found out today, was also available as a pdf. Since I got mine at different, non-affiiliated stores and they had identical production values, i highly doubt that the stores themselves printed them.

How rare they were, though, I can't say. Again, I saw them in stores all over the Dallas/Fort Worth Metroplex...but then again, I'm in the Dallas/Fort Worth Metroplex, which is in the top 10 population centers in the USA.
I think your assumption that no stores knew about the online conversion articles is false. Your store didn't know - but then your store also had an apparently rare or printed conversion guide for 2e to 3e, so your store seems to be rare fairly consistently.
I shop in 3 main gaming stores- 2 solo stores and a large, local chain- as well as a couple of national chain bookstores. Nobody knew about a conversion guide.
You are speaking for who else exactly here?
For myself, obviously, and my technophile buddies- as mentioned, 2 of whom are in the (computer) gaming industry, and, it would seem, those others who have posted in this thread with the same experience.
Its not like a host of 4Ed non-adopters haven't posted about the lack of a conversion guide before- its a fairly common complaint in the Edition Wars threads.
Again, I don't think you can say with confidence that the extraordinarily small sample group of your players can speak for the world on this topic. I think most people knew to go to the WOTC website for additional information because that fact is mentioned in the 4e books (all three "core" books say it), and anyone who did could have seen the set of conversion articles.
4e REQUIRES someone have some basic internet access, in order for you to get some essential information such as errata. For that matter, so did 3e, and 3e also mentioned their website in the core books. I think at this point, everyone knows that someone in their group should go to the WOTC every once in a while to see if there are any important things there for the game.
And heck, you know how to use Google. I found that conversion article ranked high when searching for any of a half dozen variations on the topic. Anyone looking for the WOTC conversion articles just had to Google the topic to find it. You didn't even need to go to the WOTC website directly to find them.
Personally, I rarely go for anyone's web-enhancements unless its required for my job.
Even if I had noticed a blurb about web-enhancements for D&D 4Ed, I probably wouldn't have gone looking for it. And since my past experience with WotC included a nice, friendly conversion guide pamphlet and there wasn't one when I got my 4Ed stuff, nor at any of the several stores I shopped, my conclusion was that no such thing existed.
But that's me.
Still, few things here:
First, as several have pointed out here and elsewhere, when interviewed, certain 4Ed designers actively discouraged persons from attempting to convert- given this, why would one then go looking for a 4Ed conversion guide?
Second, as someone has pointed out in this thread, when WotC was
directly contacted regarding a conversion guide, they were NOT directed to it. Whether this was a lack of WotC telling their own employees these things existed or whether it was the result of a policy that reflected the aforementioned hostility towards the conversion process I can't say. But if the publishing company itself doesn't acknowledge such a thing exists when asked directly about it, why in the world would I continue looking for it? That's insane.
Last- and this may amaze you- there are certain people on this very board whose internet access is limited to say the least. We have military who may not be permitted to download certain things or access certain sites, we even have people who visit here who are still on dial-up because that's the best thing available...so web-enhancements are essentially valueless for a variety of persons who would be looking for some of these things.
