It isn't just about price but also quality, because you are buying as an investment. I can show people some real examples of security grills for example where the quality just doesn't even come close on 2 Eagles next door to each other
There is some tiling and ground work going op where the excavations are not deep enough,with my background I know thois, the base is a joke for the tiles to go onto, but of course it is cheap price, it won't last but it is a cheap price
AC yes you can go buy units from Leroy Merlin but for for arond €100 more you can get LG units fitted with a guarntee via a reputable Spainish supplier
You need to get multiple prices, check the quality of the supplier and not buy ONLY based on the lowest price, the vultures are circuling Sierra Golf again, one company recently quoted €1600 more for AC than the prices that I had
