Almost all consoles you can see in game shops, shopping malls and online store nearly have the same price, besides maybe for some old stocks that a particular retailer want to dispose because of the introduction of the new model like the PSP Go. Other than that they generally have the same exact price. Obtaining it online might save you a great deal of cash rather than buying it personally due to the fact you also have to consider other expenditures like fuel for your car not to mention the quality time you will be spending.
If you really want a cheap brand new PSP you must look for a shop that offers smuggled items, they sell it lower than you would normally buy in almost all shops due to the fact they are not paying tax for it. This sort of practice is very popular to third world countries like Asia. The only negative aspect of this is that you might not get the warranty because they are not really an official distributor. Some shops like this may give you a warranty but they do it on their own, they usually have their own staffs who know how to fix them. To attract more buyers they even offer free games, you can choose many game titles as many as your memory stick can hold with no additional cost plus additional 24 Volt battery pack. And that is not all; they also provide some standard accessories like NiCAD battery pack and screen protector also for free. Not all country has these kinds of stores; they are only famous in third world countries that do not have existing strict regulations and policies about promoting smuggled items.
While some people want to buy cheap PSP Go, others have got more than one of them. It’s not that they bought 2 of them at a time, it’s just that they probably have them as a birthday gift or they purchased a newer version of PSP. If you have a buddy or you know anyone who owns spare PSP why not ask to buy it. I’m sure they’ll going to like the idea since they already have new one.
