IMO price is of course always important but warranty issues , ability to buy a box to test are more inmportant . Do you they have enough of one "dyelot" to do your whole job . Too many things need answers and no one can help with that but you. Compare apples to apples always . In my experience discount flooing places often have castoffs and not enough of one type and color to do big jobs that is why they are cheaper . And of course always go to the store no online shopping for flooring
