Don't buy anything from PC World superstore. They will rip you off. The service is terrible, they are overpriced, dishonest, insincere, greedy and incompetent. Their Galway shop is probably the worst of all. If you buy computer related products in Ireland, hardware of software, just get them abroad or on the internet (komplett.ie, K&M electronic, notebook.de). For example, in the Netherlands, the computer keyboard is also QWERTY and Windows XP is in English + you have 2 years garantee on many products.
I bought an item from PC World that was overpriced and half works. PC World claims it works perfectly: as a result won't take it back or propose any arrangement. They are just interested in taking your money but don't give a damn about you or the quality of their products. I know many people who are entirely dissatisfied with them so do not do the same mistake.
