I know you're trying to be facetious and silly, but you **do **realize that every jackass here in the States now stipulates 'No boxed gifts please!' on the wedding invitation (i.e: bring cold hard cash or don't bother to show)?
That said, the dollar's been declining in value, so I'll probably be asking for gold or silver bullion at my shaadi.
depends. I have attended two weddings of former classmates who didn't specify cash, etc. one even asked to not be given any gifts. but these were very polite, classy type of guys who I've known for a very long time.
having said that I like giving cash now. I gave pretty fancy gifts to those guys. and it turns out in retrospect, they were of no use to them. might as well have given them cash and made it easier for everyone. I wouldn't have to think of a thoughtful gift that both persons would like (we're talking about something better than blenders and something that would cost a lot more than the normal amount of cash given) and the couple gets cash which they can use for whatever they like.
and I don't think the dollar is going to become worthless between the time you get the cash and the time you go deposit it into your bank account.
