I’ll just say it straight. Good quality simply costs money. Cheaper is always possible in the truest sense of the word. Here, quality can vary enormously. What is the construction of the floorboard, i.e. carrier material, wear layer, etc.? Click systems are also different. By groove you probably mean a continuous V-groove. So my advice would be to go to a specialist retailer, look at different floors, touch them, and get advice. Haro is certainly one of the leading manufacturers, but there are definitely others that deliver good quality as well. And ordering over the internet (if I interpret your post correctly) is not always the ideal solution.
