Hmm, well we used to sell hundreds of products each week, now we don't. Those customers obviously liked our site & products now they can't find us! FAIL!
Look, it's not up to Google to make your customers find you. Go buy some adwords, or send product to bloggers to rate, or undertake any other kind of marketing that doesn't depend on free traffic.
Quite probably, your potential customers are now finding a similar product, and are quite happy with the situation.
Money is not being "lost". It's being redistributed. If you're not happy, then change what you're doing. Adapt to the new reality. Launch a bunch of highly focussed, highly targetted micro-sites. See how that goes, or re-write your content so it is totally unique. Go build some links. Anything other than demand Google gives your traffic back
