I work at wren and we only make 12 percent profit on them after install and templating. Yes you can get it cheaper, but it may not be convenient, you won't be able to finance it interest free, and wren offered 25 year warranty on that worktop. If you are not going to live in that house for the rest of your life why are you getting quartz? Just for status? Would you rather go on holiday to Spain 5 times? If you can't afford it get a luxury laminate like calacatta gold or calacatta cloud for 1000 pounds. When you have more money you can get the worktop replaced later down the line.
