What people seem to not understand these days is that discount stores of all types only pay minimum wage. Business can not afford to pay good wages for good people and then discount everything.
On top of the minimum wage, the business must pay taxes, insurance, workman's comp etc which results in about 33% more than the actual employee receives.
Remember,you get what you pay for!
No, I don't own a store but know a number of small business owners who struggle to meet payroll every week.
