Speaking of wine and cheese, Crate & Barrel's similar scanning-and-scarfing registry events have made it also hugely popular in the wedding world. Roughly 26% of all couples registered there last year, up from 24% in 2009. Bridal brunches -- they let couples scan items into registries while busying themselves with little waffles made in store-sold waffle irons, breakfast sandwiches cooked in straight-from-the-shelf Cuisinart Griddlers and champagne-spiked mimosas mixed in glassware available in the catalog -- have only increased the store's appeal. A completion program that offers 10% off the price of registry items after the wedding -- which Knot and WeddingChannel registrants said was their No. 1 motivation for picking a retailer's registry -- doesn't hurt either. If there's any downside to Crate & Barrel's success, it's that -- according to Eisinger's findings -- the average Crate & Barrel registrant tends to be a bit more wizened than his or her coupled counterparts. That maturity brings a bit more expendable income with it, but it also means the low-end, post-collegiate cheap stuff that helps broaden price selection is mostly missing from the crates and barrels.
