Is the laundry ball expensive?
Not expensive!Retail price of the laundry ball in 100 times package is about RMB. According to calculation as 2days/time for common family, one ball in 50times can wash 4months, two balls can wash 8months, it only needs to purchase 2boxes laundry balls for one family in one year, namely RMB is enough. But for washing powder, according to calculate as 2bags/month, RMB for common family, it needs to spend more than RMB for one year. Comparing between them, bright customer, do you think which one is more expensive?
