Competitive prices and very reliable

Came across the monitor I was looking for with very decent discount - made the purchase and order went through but there was a stock issue.
Contacted Jim who responded promptly and offered full refund immediately or to wait for a new batch to come in and deliver with original pricing - which I went for.
Better process and communication than many big name operations, would not hesitate to use again and will recommended to others.

Very happy with the refurbed laptop. Perfect for what I wanted as a low-cost occasional use remote working laptop. All MS Office functions worked well.

Absolutely brilliant customer service from Jim himself. Jim was very quick to reply to my email regarding a tracking issue, and even followed up personally to make sure the product was in my hands. The product is top quality and honesty unbelievably priced. I've seen other competitors, including Amazon.ie, charge at least €150 more for the same SKU of 9070 XT. My order was dispatched within 1 working day, and I received it within 2 days. I will definitely be buying from Valu PC again

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.
