I found Registry Perfect right after signing up for Product Hunt, and they've earned my first review quite instantly (and I already sent their website to a few of my friends who are getting married).
From a design and product standpoint, I felt like the experience was much simpler and more direct than other registry websites, while still having all of the same stores I always see on other registry sites (..but without the same hassle and culture):
The reason I'm sending this to my friends, and even writing this review, is because I always found the traditional registry culture to be so outdated, and the flexibility that Registry Perfect offers the Bride and the Groom just makes me feel better about my gift.
Good luck and I'm excited for new updates!
