I'm pretty easygoing with this kind of thing. I figure if someone puts in on their registry it's something that they need or really really want, even if it's not a traditional "wedding" item. For example, I could imagine the Ann Taylor request as being to buy a new interview suit as the bride is going to graduate from college just after the wedding, or the couple is moving to a new place, etc etc. I suppose it depends on the couple but you tend to know whether they are just being greedy or trying to steer their guests' gift-giving desires into something that is practical for them.
For this reason even ostensibly tacky practices like the "dollar dance" (where you pay a dollar to dance with the bride for a few turns) make sense in some cases. One of my uncles orchestrated this at my younger cousin's wedding, and as everyone knew they were struggling financially and had a baby on the way it was an entertaining way to slip them a little bit of extra cash. And, well, we are a rather, uh, "down home country" family. So a few redneck practices seemed entirely normal!
And honestly I greatly prefer it if all the wedding-related info comes to me in one envelope. Much harder for me to lose track of it that way, and not everyone has a website! I think that every invitation I have ever received had some kind of gift or registry information. I have never felt pressured to give a gift that was more valuable than I could afford.
We put gift information in our wedding invitations -- we really wanted to emphasize that no gifts were necessary but since we knew that people would want to get us something anyway we asked for gift cards from a handful of stores. Bridal showers are not a British custom, so all of our UK guests would have brought gifts to the wedding if we hadn't said otherwise. In our case my family was flying over from the US, we got married on the other end of the country from where we were living, we don't have a car so we travelled by train, and we were still living in a tiny student flat with no immediate plans to move. So it really made no sense for people to try and stuff gifts into their suitcases (in addition to paying for the trip in the first place!) or give us things that we couldn't take home on the train or fit into our flat.
And even though individually people generally gave us about £10-20 worth of gift cards, collectively we were able to buy all the necessary appliances for our house a few years later with them. It was what we truly needed but of course we could not have put a stove and refrigerator on a registry list, nor could we have stored them for 3 years waiting for the eventual opportunity to move.
