I heard that 90 daya super wash card cost about 200$ after tax , you can use the card to wash once a day. if 4 persons share the cost , eash one cost 50 $. but you have 90/4=22 times super wash in the 90 days. remember 1 time superwash costs about 12$ - I heard. so that is a value of 22 X12 =262$ for one person. so share the cost is a good idea.
