Markets vary with location too. Some of us don't live anywhere near a big chain store that sells on the cheap. Make sure the AD you are referring to is current too. AKs in particular that got caught up in the recent import ban still have cheap sales ads floating around but are out of stock. They may actually be worth more now despite the AD price due to lack of availability.
In regards to the big chain store, the internet wins the day. No need to go to stores when you can get great prices online. Sportsmans Guide, etc.
