Celebrate marraige (ok, I`m a bachelorette and mom) and include info on your site . . . but if it is a business, HOW do you plan to make money. It should at least be self-supporting. Therefore, the gift should still be a part of it, perhaps interwoven with ways to celebrate and be greatful. For example (forgive me because I haven`t checked out your current site for the types of gifts you offer):
One way to celebrate is through an intimate dinner for you and your spouse, followed by a bubble bath for two -- champagne included, a massage, etc. And then you offer whatever appropriate gifts you have (candles, gift baskets of bath bubbles and massage oils, robes, etc.) from your shopping cart.
Well, it`s a thought. Good luck with the redesign.
