I went to Merchandising and I do not have a button for coupons? Any idea why?
Yeah, it's because your store is ShopSite Starter. The Coupon feature is only in the ShopSite Pro product level. Talk to your hosting partner about upgrading to the Pro version.
Also, I noted that at least some of your order links don't work. For example, from this page:
http://www.getcertifiedquick.com/meshspecial.shtml
This is probably because of the 8.1 in the link URL, your host may have recently upgraded you to ShopSite Starter v8.3, so try changing the 8.1 part of your order links to 8.3 and that should work for you.
