I think Sirius already said this, but I really don't get why people *ask* for money.
We didn't ask for anything, no wedding list, nothing. If people asked us what we wanted, we said, "we don't really need anything, if you'd really like to get us something then you could make a donation to the charity of your choice in our honour".
Some people did that. Some people gave us tangible gifts. And some people gave cash. More than enough cash to pay for a lovely honeymoon (the total was well into the £XXXX.XX amount).
So if people really want cash, don't say anything at all. Same result, and happy guests who've given their choice of gift.
I'd venture to say that some people are just plain greedy, but it's not always that--I went through this with my now-DH, whose character is frankly impeccable.
We live overseas, but our wedding was in the U.S., and it just drove him crazy to think that well-meaning guests would give us tangible gifts. I got it to an extent--between shipping and customs those gifts would cost us money, and they could theoretically cost us a lot.
I believed that we could solve the problem by just not registering--I assumed that people would take the cue and either skip the gift or give some money, especially since they all knew we lived so far away. DH absolutely did not agree. He was positive that a substantial number of invitees would pick out some lovely-but-bulky thing instead, and since we hadn't registered they would all be from different stores, making returns a pain if we just couldn't handle the cost of shipping. In other words, he felt that the cost if I turned out to be wrong outweighed the rudeness of directing people who asked about gifts toward money.
And the fact is that he--we--did
want money. Not in a "people who come to our wedding owe us and should cover their plate" way at all, but in a "money is a nice thing to have" sort of way. We weren't hurting for money or trying to recoup costs, but...well, who couldn't find a use for a gift of cash? The difference was that, while I'd been trained from an early age never
to acknowledge that (even typing it here feels horrible!), his family has always talked openly about money and had a long-standing tradition of requesting specific gifts from each other. From his point of view it really wasn't different from what he'd always thought of as fine...and I was cutting off my nose to spite my face.
(After numerous meltdowns, we settled for creating a registry in our country of residence--although even with a great tutorial only a handful of people braved that website. Most did end up giving money...and we still got a huge box's-worth of assorted beautiful things, most of which are still in my parents' house five years later. DH asks me about it whenever we argue about a point of etiquette.
