RE: CABELAS or GANDER MOUNTAIN
I worked at a Gander store for 3 years and we had a lot of people come in because they liked our store better than a nearby Bass Pro. That's when Gander gave a hoot about customer service; something that slowly went by the wayside.
That being said Gander's prices were usually just a bit lower than BP or Cabelas, but truth be told none of them are any great bargain stores. Their prices are pretty much MSRP unless there are sales going on.
As for archery supplies? They carry very little, if anything, that I would be looking for. Just common old ordinary cheap sights, rests and such.
