I would also check out CVS and Walmart. They have very competitive prices with Walgreens and are definitely worth comparing. If you are a new customer at the pharmacy you may qualify for a special offer or coupon. Check the store ads for that discount. Good Luck!
I work at Kroger's Pharmacy and we do $5 and $15 dollar prescriptions if just depends on the quantity ad the amount of refills. But if you don't try there definitely go with Wal-Mart (: hope this helps !
