Get a free 2 oz. travel bottle of Biotrue multi-purpose solution from Costco if you are a Costco member.   Not all the samples that Costco mails out require a membership number, but this one does.  If you are not a member, please wait because these samples often open up to everyone after a few weeks (I’ll let you know).  You should receive your sample within 4 to 6 weeks.  You can also print a $2 coupon to get BioTrue for free at stores that sell the 2 oz. travel size.
