If saving money is the object, then yes, wait for the initial rush before you buy a new firearm offering.
But just think of all of the enjoyment you would have missed out if you had waited weeks or even months before making the purchase. Sometimes it is just best to bite the bullet and make the purchase, within reason of course.
I will sometimes do that on a brand new firearm offering, but I refuse to go over MSRP. All of the people with money to throw away can buy from Gunbroker as much as they want, but MSRP is my limit, and even then you can offset that by buying from places that offer free/reduced shipping cost and those that don't collect sales tax.
