Here's a question for you all. It has come to my attention that looking around the shops like halfords and such the price of ice is very expensive when compared to the Internet. Now it would be clever to buy the stuff off the Internet and then have it fitted by a pro. My question is, if you do buy off the Internet and then have it fitted by a pro what type of garantee do you have? Say if the unit went wrong and you went back to the internet shop would they be difficult about the warranty because someone else fitted it? I know halfords offer fitting of head units and such so if anything goes wrong you can go back to them. The reason i am asking is because the price difference is massive! £700 in some cases. Why is this?
