Previously, I had compared the price of Allergan Refresh Plus at Target and Costco.
Wal-Mart sells a 30 single-use containers for $6.98 (or $0.233 per container) or 70 single-use containers for $13.94 (or $0.199 per container). Recall that Target sold the same 30-count box for $6.99, or one penny more than Wal-Mart. As usual, Costco sold Allergan Refresh Plus for lowest per unit price—$0.184 per single-use container.
