OK, here is my story and it might help get your gun cheaper.
I went to G.M. to look at their E callers. Found the one I want and they priced it at $489. I went home and in the Cabela's catalog it is $269. I brought the ad to G.M. on sunday during their grand opening, grabbed the caller and took it to customer service. I showed them the ad and they could not believe the price difference. The manager came over and gave his approval. They matched the Cabela's price, took an additional $50 off, and I used my coupon they sent me in the mail for $10 off good during the grand opening weekend. So I paid $227 incl. tax for the caller, and did not have to pay shipping. I thought that was a great deal. I do not know why they took the additional $50 off and if they will continue to do that, but I am glad they did. So if you can find an ad with the price of the shotgun, G.M. will match it and maybe take an additional $50 off. It is worth a try.
Good Luck
