Version iPhone without data package?

So I love my iPod! Pretty much everywhere I go there's Wi-Fi so I use Wi-Fi a lot! I thunk it would be nice to have an iPhone instead of a phone and an iPod. I don't particularly want a data package since a) Verizon's are super spendy! B) Wi-Fi is everywhere in my town
And c) it's ridiculous!
So can I buy a phone from a cellphone store that doesn't sell plans and just have them put my sm card in an iPhone and not have a data plan?
