The biggest reason I use Giant Eagle's 12th Street Pharmacy is simple, drive thru service. I love the convenience of being able to call in my order or order refills online and simply drive thru for pick up. The fact that you can also order your refills online, any time day or night, is a big plus in the convenience area! The clerks are generally pleasant and if you have a question the pharmacist is quick to come to your call. I hate calling in the order as it takes forever to get thru their stupid phone system. Ordering online is so much easier.
Price wise, Frontier Pharmacy beats them every time but I do believe they will price match if it's an issue for those who don't have insurance or if your insurance doesn't pay for the prescription. They do sometimes come up with the same price as Frontier but rarely. Not really an issue when you have insurance and standard co-pay I guess.
