Wouldn't normally bother with review's but I was really impressed with ValuPC, despite never having heard of them before. While googling a specific laptop model I noticed that they're cheaper than other psychical stores by over €200. I ordered the laptop late one and 2 - 3 it was at my door. Excellent service fast and reliable and have already recommended to others

Was going to go to an English chain of computer shop, googled and seen valupc. I ordered a new laptop and Monitor late Sunday night and had them in my hands on Wednesday morning with everything working as expected. I would recommend Valupc as they are Irish and defiantly good value, will be back in the future.

James

Great deals on the market, which seemed sketchy, but decided to order a monitor anyway. Was delighted to know that I was wrong, The monitor came in perfect condition, nothing bad to say whatsoever. Even had some problems with the delivery and they helped me out! It's a great site to buy electronic things of off, don't think twice about it.
