mtbc | Alternative online vendors

While some online merchants rather benefit from their dominant market position that isn't to say that there isn't room for competitors to rise. As one annoys me I look at using others, for instance moving from Amazon to eBay then to eBid or whatever. Unlike, say, car rental companies where it might be a matter of using the one that last annoyed me the longest time ago, there is plenty of room on the web for new marketplaces to grow. It would be nice if it were easier to consult an up-to-date if only with some irritation you buy X from Y then consider patronizing Z instead. Some searching online finds helpful articles but it all feels a bit random.
