If you don't a need a new computer, printer, or other accessory immediately, take a look at the websites listed below. Many items will appear sooner or later at a considerable discount, directly from the manufacturers website. Danger: these websites will cost you money (and I don't mean subscription cost)!
When buying on ebay, it is recommended to buy from sellers that have at least 99.5% positive feedback and at least 100 transactions. Esnipe - online sniping tool, enters your bid in the last 7 seconds of the auction. Cost is 1% of the final cost of the item if you win (no charge if you do not win). Prospector – “advanced buyer tool for collectors and bargain
hunters.” Allows you to save complicated
searches and revisit them and to view all items as a list, with the seller id,
their feedback, and how many items available. Normally you would have to click
into each item to see who’s selling it, and what their feedback rating is.
Before you buy the biggest, most expensive ( blank ), ie router, check the user ratings. A great website is www.newegg.com, where geeks do their daily shopping and write fairly accurate user reviews. And Newegg has a mobile version of their website ( m.newegg.com ) designed to be viewable from a cell phone.
