OptiContacts – False advertising

Saw advertised price on contacts with a coupon for $15 a box . Went thru the whole process of ordering get ready to check out says total is $111 total. Then hit ship order and then that page said $247 .They added on a $89 processing fee and $19 shipping . So I then wanted to find out if they charged me $89 processing because they gave me coupon discount so I made an order without using a coupon paying full price for contacts and the processing fee dropped to $14 with free shipping . So they are false advertising because if you use coupon code they get it back by charging you a high processing fee . The contacts were the same price either way. This practice should be against the law
