(NPN) - Before young couples walk down the aisle, they traditionally sign up for their gift registry, scanning fine China and linens.
However, no some are warming up to the idea of ditching the dishes and asking for cold, hard cash instead.
Lauren Caproiotti and Nick Guerin are getting married and plan to make their outdated house into their dream home. With their wedding around the corner, the couple decided to try something nontraditional with their gift registry.
"We requested cash because we had so much work to do on our home, and we realized that a lot of our finances over the next two to six months after the wedding are all going to go into these renovations," Capriotti said.
For the bridal shower, they asked for Home Depot gift cards. For the wedding, they signed up for Tendr, an online registry where guests can use a credit card to add to their renovation fund.
The couple are part of a growing trend of wedding partners asking to fill their wallet instead of their cabinets.
"Couples today are living together well before they get married, and so they already have dishes and glassware and lines and towels," said Anne Chertoff, a contributing editor for Yahoo! Style. "They don't need register for more of those items."
Chertoff said some relatives may be turned off by the thought of bridal couples holding out their hands for cash.
"You don't want to come off as greedy or crass," she said. "And so it's a really fine line that you make sure you find a registry site that's reputable and also something that looks appealing and secure."
About a dozen online wedding registries offer cash as a gift choice, but there is a catch.
"There are fees associated with those services," Heather George, the associate director of wealth planning and analysis at AB Bernstein. "It's not necessarily that you shouldn't use them, but you should be aware of the fee associated with using the online registration."
Despite those fees, more millennials are including cash in their registry.
"If you can make a decision that creates a greater sense of financial security to you as a couple from the start, as part of your wedding, that to me for sure has to have an impact on improved success down the road," George said.
George added that, because millennials grew up during the recession, they're likely to put their money toward practical purposes.
According to a survey by Tendr, 64 percent of users use money from the registry to pay for debt, home improvements or purchasing a home.
Etiquette experts recommend couples do not just give their guests their bank or Paypal account information. Instead, they should request checks or sign up for an online cash registry.
Those can charge anywhere from 2 to 8 percent, but they also offer customized options to describe the fund.
