the answer is yes and no, some shops drop there prices when they go and others dont. it just depends on the shops normal price and there overhead (how much they already go over they cost of the firearm) some can come down and others cant.
Some on here usually post their 1500 deals prior to the 1500 and some even offer special pricing for INGO members. I'm sure we'll start seeing some of them next week.
Going to the 1500 is kinda like shopping the day after Thanksgiving.... there might be 3 or 4 doorbusters but you can get everything they have there for the same price or cheaper online
With the cost of gas today, the admission to the 1500 is a deal compared to driving around to 5 different shops.Depending on where you live there are probably 3-5 gun shops within a 30 minute drive. So if your goal is just to get a feel for some different guns do it for free. If you want to pay admission and be herded around like cattle...the 1500 is sometimes worth it.
