I wouldn't ever compare Gander to Dick's. Gander is expanding their firearm selection as well as ammo. They are also expanding a lot of stores to include live fire, virtual and virtual situation ranges. Gander is high priced but not gouging or inflating due to any kind of panic.
Dick's on the other hand used a tragic event to discontinue selling the AR15 AND cancelled THOUSANDS of orders from a sale on Troy AR15 Carbines that customers had already paid for. This was pre-panic. By the time customers were notified, we were well into panic buying and AR's more than doubled in price leaving all those that thought they had an AR out in the cold.
Yes, both are large stores but completely different stances on firearms and customer satisfaction.
