Did you know that since May, it has been changing, and that by October only those business who PAY Google will be able to have their products show up in the Shopping search results?
Personally, I have found it to be a very good way to research the prices for fabric etc. But going forward, the businesses who pay the most will show up at the top of the listings. You'll have to sort the search results by price, to find the lower-priced listings from shops who can only afford to pay a little bit ... and those shops who can't afford to pay *at all* will not show up *at all*.
Google says this should create a better shopping experience... but if the low-overhead/low-price businesses get weeded out, how does this help the shopper?
