Went to Costco today to refill on contacts (my prescription expires in 2 weeks) but they told me I could only buy 1 box. Also they said there was a limit of 8 boxes your could buy in a year? Is this true or are they just trying to get me to see their optometrist again. I think it's ridiculous because I have the rx so I'm not going to get the wrong kind of contacts and it's not expired yet, do i HAVE to go see my optometrist just so he can re-write a script?
