We started a registry just because we are buying double of some items. It's more for our benefit (we haven't told anyone, even if they have asked) so we can get the registry rewards. BRU also lets you combine the registry completion and multiples coupon so we plan on using that for big items. We set our DD two months ahead so we can get the coupon sooner.
@nsquaredlife13 Awesome! Did not know that!
