If you're wondering if it's worth buying something on eBay because it might be readily available and cheap on Amazon or vice versa, Q-Compare can help you comparison shop between the two services.
Click on the image above for a closer look.
At Q-Compare you select the country you're in and the category you want to search in — you don't have to specify the category but it really helps narrow the eBay searches — and Q-Compare displays potential matches, seen in the screenshot above. In the sample search seen here, we were searching for the board game Mr. Jack.
Once you select from the initial selection Q-Compare shows the item on Amazon.com and a selection of thumbnails of the item for sale on eBay. One big perk that comes with using Q-Compare as oppose to the Google Shopping is that the results provided by Q-Compare for eBay are for current auctions only, you won't find any stale auctions in the mix to throw off your price comparison. For Australian buyers, of course, postage is a major consideration, and lots of categories of goods from Amazon won't ship down under. However, if you're looking at books or DVDs and both sites are on your shopping radar, it can save you a few steps.
