returning vinyl for warpage?

Ok so I am kinda new to vinyl so I am not sure if I am just being too picky so here is the deal:
I purchased 2 new LPs, Beatles white, and Them Crooked Vultures. Both are double lp, and the first song or so has a noticable warp. They play fine...but it's awful nerve racking to watch the needle ride up and down over the waves LOL. I have purcased about 30 records new from the same store and never had this problem before. Since they play fine, is it unreasonable to go back and request another copy? TCV wasn't that big of a deal but the darn Beatles cost a chunk of change!

thanks for your input.
