If you're not interested you can skip this part
------ This happened to me not long ago, and I made a thread about how annoyed I was with Encargopaq. But anyways. My laptop in February was about to die,(it still works, not good, but it powers up and so on) so I needed something else. For a lot of reasons, I prefer a desktop, although a laptop is in many ways more convenient. But anyways. So I ordered on Amazon the Motherboard, CPU, memory, hard drive and Power Supply. I ordered everything in separate packages so that every package would be under 200$. But guess my surprise when Amazon decided to ship everything together. To no avail, I tried contacting Encargopaq to see if they could separate them, as I had different invoices for each package. But no answer. So when everything ended up here at customs, they only saw one invoice for $180 and realized that it was not a complete invoice. It took me a total of 6 weeks to get the package released from customs. And I had to pay almost $200 in tax and courier fees, (the total value of the package was around $450). ------
So in this case, YES it's way cheaper to buy from like Amazon, Microcenter or Newegg you name it. But if you are going to buy a complete Desktop, take into account that there might be a struggle with customs, and you would have to pay at least 20-25% in taxes and fees (depending on your courier). And to my surprise after buying the parts, there are actually quite a lot of more "expert shops", especially in the DN area that sell newer desktops for a decent price. So my suggestion is, either to go to one of those stores (not from stores like Ceducomp or similar as they only sell old used 2nd hand Dell/HP computers, although being quite cheap, are totally worthless), or to buy the pieces and build it yourself, but then to not make my mistake but order the parts REALLY separate. Make one order and then wait until that order has been shipped, and then continue with the other, and everything under $200.
Or if you live in Sosúa area, you can go to Ramon in Copicentro and have him take a look at your computer, a german guy with a lot of experience.
